Yes, read the handbook first and then ask specific questions.
You need to do your homework.
This shotgun style of question will not get much useful response.

But, making a mail server with FreeBSD is so easy.   Unless you
want to do something weird or exotic, then FreeBSD already comes
with a good mail server all installed.   All you have to do it
enable it.Put  sendmail_enable="yes"  in /etc/rc.conf and
the next time you reboot you have the most common mail server running.
It will receive and send Email just fine.   Then you might want to
install mutt from /usr/ports/mail/mutt  or some other Email client
to help you read your Email.  Of course, you could just use the 
already installed 'mail' utility.   

If you must have a web-based Email reader, try installing squirrelmail.

I believe postfix is considered to be much more secure and better then
sendmail overall. I have a mail server and find that postfix was pretty
easy to setup and configure. In addition, it is easy to manage with qshape,
which installs along with Postfix.

The Postfix website has great documentation if you are interested in going
this route: http://www.postfix.org/documentation.html

[AN]

I'm getting ready to install a new mail server.  I want to configure 
sendmail+clamav+spamassassin+mimedefang.  Does anyone have some pointers 
or  howto docs to share?  I read somewhere that spamassassin-milter has 
security issues.  Is mime-defang a better option or should I consider 
something else.  Any help is appreciated.

Well, i think you should move to Google Apps. It's very safe,
reliable. And several big guns use it. An example is below:

lots of stuff is mis-configured.

If you have people outside your network addresses trying to send mail 
through your server, you need to be running a 'mail submission agent'
on port 587, as well as the MTA on port 25.  If you're not doing this
already, you'll have to set it up.  Since this access is password
protected, and available only to your 'trusted' users, it does -not-
need spam-filtering on it. (usually, that is -- you know your customers
better than we do :)

*AND* the client using Outlook Express needs to configure _it_ to use your
server *on*port*587* as the 'outgoing mail server'.

This will require entering 'authentication' information (username and
password) into Outlook Express.

Please see:

http://spamassassin.apache.org/full/3.3.x/doc/Mail_SpamAssassin_Conf.html#network_test_options
http://wiki.apache.org/spamassassin/TrustPath

"Why should trusted_networks and internal_networks ever be different?

A mail relay that you want to trust in trusted_networks may itself trust its 
own internal dynamic IP networks. You may trust them not to be a spam source 
but putting them into your internal_networks list would create a false positive 
because then those dynamic IPs would be searched for in the DUL lists. This is 
an example where the two lists need to be different."

If need be, also consider whitelist_from_rcvd (or maybe whitelist_auth if you 
implement SPF or DKIM).  I'm also told that something like:

  meta AUTHD_RELAY !__LAST_UNTRUSTED_RELAY_NO_AUTH 
  describe AUTHD_RELAY Message submission was via an authenticated user 
  score AUTHD_RELAY -10 

I believe there is even an optional patch in the spamass-milter port:

  
http://www.freebsd.org/cgi/cvsweb.cgi/ports/mail/spamass-milter/files/extra-patch-addauth?rev=1.2

...but it is probably better to just tweak the scoring a bit.  Or switch to 
using amavisd-new, which could allow greater flexibility also

When someone is an authorized user of email, ie, they login to your SMTP server 
via a good username+password, then you should configure your spam filtering to 
treat them as trusted.  For example, in postfix you could have:

smtpd_recipient_restrictions = permit_mynetworks,
permit_sasl_authenticated,
[ ...before checks like... ]
check_policy_service inet:127.0.0.1:12525,

Dear Dr. Matthew.,
 
   When my client or any clients uses the web mail that i have configured, 
   then everything works fine NO spam problems and email will be
   received by hotmail, gmail and vise versa.
 
   I found out that this particular client complaining because they use
   outlook express NOT the web mail.
 
   they configure their outlook express to use SMTP user/password
   with mail.clinet_domain.com as incoming/outgoing.
 
  even if they send from x...@client_domain to ad...@mydomain.com
  both are in same server, I will still receive it as SPAM.

This is certainly possible.  It would add spam points on my servers.

The address in question is the one presented by your mail server during
the SMTP dialogue -- the first line it sends in fact.  Something like this:

   EHLO smtp.example.com

By default it will use the hostname of your server, but you can override
that.

It is this address that you have to be really strict about: the address
should resolve to the IP that the server connects via (not necessarily
the IP of the server if there are NAT gateways involved), and a reverse
lookup of that IP should return the name again.

This name used in the EHLO banner doesn't have to be anything to do with
the addresses on the e-mail, except in as far as either side is using
SPF and you have chosen to add that information to the SPF selector(s).
 SPF seems to be going out of favour now, and sensible mail admins
didn't make accept/deny decisions entirely on pass/fail of SPF tests,
but still, for best results with a mail system, you should take care to
get that right.

Cheers,

Matthew

Since you didn't provide an example DSN or even anonymized logs of a bounce, we 
can't guess-- in general you'd discuss a specific bounce message with the 
postmaster of site which bounced it.  As for hotmail.com, they can't even be 
bothered to make postmaster@ work:

  http://www.rfc-ignorant.org/tools/lookup.php?domain=hotmail.com

...which means they're sufficiently broken that you should expect mail failures.

My mail server flagged spam!

[Marwan Sultan]

Hello list..
 
  Well! im kinda lost here..
  I have like 8 domains hosted in my server. FreeBSD 7.2R, sendmail, 
openwebmail, spamassassin, milter all installed.
 
  I have few customers complaining that thier emails (the domain they send 
from) to hotmail/yahoo..etc..
  flagged as spam! i have googled and found most of problems about forward, 
reverse DNS.
  for me PTR, reverse DNS matchs the domain name. all the 8 domains matchs 
reverse, PTR.
 
  if I check that domain in mxtoolbox.com
  it complains "Warning - Reverse DNS does not match SMTP Banner"
  could it be the SMTP banner flagging the mail as spam?
 
  ofcourse the SMTP banner matchs 1 domain out of the 8. which is my server 
main domain.
  SO if anyone sends any email from my server the SMTP banner will show my 
sever name.
  this one should not be a problem isnt?
 
  Now the case become worse! the same customers who are using that domain
  complaining that even if they send to the same domain name x...@domain1.com 
to y...@domain1.com
  same domain to same server.. its flagged as spam too.
 
  No, none of my domains in any black list.
 
  Anyhints please?
 
  Thank you

Looks like you are trying to coax me into running Postfix! I am an Exim-er

On FreeBSD /usr/sbin/sendmail is a link to mailwrapper(8), which is a
part of the base system.

For starters, you are using the wrong sendmail. You need to use the
Postfix 'sendmail' version.

$ which sendmail
/usr/sbin/sendmail

I have Postfix installed and running. Sorry, I thought that was obvious.

Typing: "man sendmail" should show this at the top of the page:

"NAME   sendmail - Postfix to Sendmail compatibility interface"

If not, then something is configured incorrectly. By the way, in order
to run Postfix, you have to completely shutdown the base system's
'sendmail'

cat /etc/rc.conf

# Shutdown sendmail
sendmail_enable="NO"
sendmail_msp_queue_enable="NO"
sendmail_outbound_enable="NO"
sendmail_submit_enable="NO"

#Start Postfix
postfix_enable="YES"

With Postfix installed, using "sendmail -bv" works quite well.

while we are on the topic of debugging I would recomend exim as an MTA. I
manage a few large enterprise mail systems with 10M + active accounts. A lot
of them are legacy systems that we gained through acquisitions. I generally
have to support them until we can get the accounts migrated onto the main
platform. They are a mixture of exim, postfix, qmail, and sendmail, and
quite often are in a poor state when we first get our hands on them. I have
to say when you are getting mail routing issues exim is by the far the
easiest to debug mainly due to the -bt option. When you combine it with the
debug flag it produced a very detailed output on the mail routing. I have
never found such a feature in all the other MTA's above.

The configs are also very readable unlike sendmail.

steps:

a) check if your dns are correct:
# dig yourdomain.com mx
(eg:)
mail.yourdomain.com
# telnet mail.yourdomain.com 25

does it reply or not?

a) reply
 check if your mta is cofigured correctly:
 telnet mail.yourdomain.com 25 # write:
  ehlo gmail.com
  mail from: aryeh.fried...@gmail.com
  rcpt to: example_u...@yourdomain.com
  data
  Subject: Test
  .

 does it reply with a
 2XX code? with a 4XX code? 5XX code?

b) doesn't reply
 does mail.yourdomain.com resolve to your mailserver's IP?
 is your daemon runnig?

p.s
if you give us more REAL information (domain, ip, etc) we can hel you more.

Microsoft has been claiming for years that adherence to standards is
not a requirement. While they are certainly entitled to their opinion,
I would definitely disagree. A quick perusal of http://slashdot.org/
would tend to discredit your remark that, "doubt anyone makes a choice
on an MTA (or any other software) based on it's RFC-compliance" statement.

As always, selection of tools and their suitability to the task is left
up to the end user.

I for one like to know that it is RFC compliant.  it's a reason RFCs
are made, so there can be standardization...  So yes, I do choose
based on compliance.  (anyone use Firefox over IE at work because
Firefox "works better"?)

I doubt anyone makes a choice on an MTA (or any other software) based
on it's RFC-compliance.
In my experience, it's normally boils down to:

1. It has the features that I want
2. I can swim with it in times of toruble

At least Postfix is fully RFC compliant, as opposed to Exim.

SEE: RFC 2034 (SMTP enhanced status codes), RFC 3461-4 (delivery status
notifications), RFC 1652 (8-bit MIME including 8->7bit conversion)
among others.

At the risk of starting a flame war, I think sendmail gets a bad rap. It's not 
been the most widely used MTA for the last few decades because it sucks. It's 
about personal preference.
 
Now I know this may be redundant advice but I used to run an MTA and enjoyed 
having the use of it and freedom to have my own mailserver at home. But alas, 
the spammers have ruined that for all of us and almost every ISP out there will 
block port 25 by default. Even if they don't block port 25 it will only be a 
matter of time before they detect your outgoing mail traffic and then block you 
so that you're forced to purchase an add-on service to run your own MTA. They 
will use lame excuses that you've been blacklisted because of spam. It's simply 
their way of making you cough up extra dough for your service. This is one of 
the parts of the Internet that I really hate and long for the good old days.

First, as everybody else: If you are not satisfied with the default 
sendmail the most popular alternative seems to be postfix, it will 
probably be much easier for you to get help with postfix should the 
problem turn out to be the mail configuration.


When you modify your DNS it may take a while before the changes 
propagate, depending on the TTL setting in your zone configuration.


You can check if the mail server is running and can deliver mail locally 
by, on the mail server, do


  $ telnet localhost 25

You can then type in manually the smtp commands, see rfc 2821. If you 
can, then it may be a dns problem.


Next, can you send out? You may well be able to send out while you can't 
receive mail from external servers for local delivery. If this is the 
case, either your DNS is wrong or the changes has not yet propagated.


If you can't, check the error messages, if there is some dns related 
error look in /etc/resolv.conf to see if you use the right dns server, 
do some dns queries to check that it works. If you use your own dns 
server, check the named.conf and verify any forwarders entries.


If you can't receive mail from external servers for local delivery, but 
local delivery works - locally. Try from a different host to telnet to 
your mail server using the ip address,


  $ telnet mail-server-ip 25

If this works, maybe your dns changes has not yet propagated.

If more time than the TTL has passed and your dns does not resolve 
correctly, check that you updated the serial number in the zone file, it 
must be incremented every time you make a modification or the changes 
won't propagate to dns slaves.


If you can't connect, maybe you have a firewall issue.

This I think should get you started trouble shooting.


I informed the client that the task is likely beyond me capabilities
but I would help recruit someone who would be able to do it at a
reasonable fee paid to them


If you found my advice useful, please donate a reasonable fee to the 
FreeBSD project, I am still endepted for the great effort of all the 
people involved in the project.

Hi Aryeh,

Here are some things that I do to troubleshoot problems like this:

- - Check if there are any firewalls (client-side or server-side) that
block the ports, tcp 25/587 and tcp 110/143 in this case.  If you're
using POP3 or IMAP over SSL, check tcp 993 and tcp 995, too.

- - Check if the listening ports are ready to accept connections with the
command "netstat -an | grep LISTEN".  Do you see the ports you expect?

- - Dumb question - are the mail server processes running?

- - Assuming the processes are running and the ports are listening, what
happens when you telnet to them from within the machine, e.g.:

telnet localhost 25
telnet localhost 110
telnet localhost 143

- - Can you ping the mail server hostname?

- - Use "dig" to do lookups on your A and MX records.  Did you bump the
DNS serial number and reload the DNS server after you added the records?

- - If that works, now try telnetting to the same ports from an outside
network using the DNS hostnames, e.g.:

telnet my.mail.server.com 25
...

- - Please send me your hostname privately, if you like, and I can check
DNS and ports from here.

Hope that helps,
Greg

Might I suggest that you supply some log entries that support your
claims. It is hard to help you without actual facts. By the way, did
you also try Postfix?

We had also tried sendmail and couldn't get that working either so I

I would seriously suggest that you consider installing Postfix. It is
in the ports tree, is well maintained and works out of the box. The
Postfix forum will be glad to give you any advice you need for setting
up and securing your mail server. Qmail is no longer supported by its
author and can be a nightmare to maintain.

I'm glad it worked. Believe me, if that simple change made it work for
you, then it was worth my headache to have spent the time to learn it
for myself ;)

For the last few years, I've only used Sendmail (or sendmail) to act as
a backup MX, or to directly deliver mail from the box I am on...hence,
it's been a while...

There may be other ramifications to using `mailertable' in your
particular environment.

I don't know how your system will react, given a default setup and a
mailertable entry.

It's possible (but untested) that if the server that is specified in the
mailertable is down, your reports might not make it to you ( whether
that's bad or good is up for interpretation... I've always known no news
as good news ;)

Perhaps Giorgos or someone else may be able to provide a better
understanding.

It's been already pointed out that you aren't providing much information
to go on, so here's my WAG of what is happening.

Changing the root alias root could work, but consider the case of mail
from the jailhost being rejected by the jailed mailserver.  The bounce
message will be addressed to POSTMASTER on the jailhost, which points to
root on the jailhost, which points back to the jailed mailserver trying
to send the bounce, which points to ...

You can examine the scenario for yourself either by listening to a
married couple on the verge of divorce argue with one another, or more
specifically, by running

  [r...@jailhost] sendmail -bv root
  [r...@jail] sendmail -bv postmas...@jailhost.server.net

The jailed mailserver is rejecting the mail and is then trying to send a
bounce and can't because it's caught in a loop that ends when Sendmail
says "Look this isn't an argument ... it's just contradiction!" and
bails out.  

Why the jailed mailserver is rejecting the mail is a separate issue.

That's from the maillog on the jailhost.  More relevant to why the
jailed mailserver has rejected the mail would be the jail's maillog
entries (or whatever logging was done by the "filter" installed there). 

Either way, for the interim I'd suggest undoing your changes, rebuilding
your aliases and consider implementing an alternate approach.  For
anyone to figure out conclusively what's happening, you'll have to
provide more information.

Thank you so much, it worked =)

My MX records are correct, i could get mail from the outside, but just
couldn't get the daily reports to deliver it.

If you hadn't of sanitized the domain names, it would have been easier
to troubleshoot...

Nonetheless, you can force Sendmail to push email to a different server
directly (overriding the DNS MX entries) with a 'mailertable' file in
/etc/mail. Here's one on a secondary MX:

%cat /etc/mail/mailertable
ibctech.ca  smtp:[smtp.ibctech.ca]
ipv6canada.com  smtp:[smtp.ipv6canada.com]
...

After the file is created, a simple 'make' in /etc/mail will build the
mailertable.db file for you and take effect immediately (much like
'newaliases').

However, it's hard to tell if this recommendation will solve your
problem though. Without knowing the real domain, we can't perform DNS
tests against it to get a better understanding of the situation.

Steve

Daily report cannot be emailed to a jailed mail server

[David N]

Hi,

FreeBSD 7.2-R box with 10 jails.

The mail server (actually its a mail filter) is hosted on the same
server inside a jail.

I can't seem to get the main server reports to be sent to the mail
filter inside the jail inside the same box.

so.. r...@localhost tries to send an email to some...@anotherdomain.com.au

The MX entry for anotherdomain.com.au points to the mailfilter on the
server (jailed).


I've changed my /etc/mail/aliases to have
root: some...@anotherdomain.com.au
and ran newaliases.

When i try to send an email i get
in /var/log/messages
sm-mta[94682]: n97LeeOw094682: Losing ./qfn97LeeOw094682: savemail panic
Oct  8 08:40:40 server sm-mta[94682]: n97LeeOw094682: SYSERR(root):

Re: Whic mail server?

[Aflatoon Aflatooni]

Thanks,
I am running Sendmail on FreeBSD and it is working. 
I have worked with Sendmail for years and have configured and using it 
successfully, but with sendmail there is so many things that you could 
configure you are not sure if you have it configured correctly. 
I generate my sendmail.cf using m4 and it works, but I find that there are 
always new changes that you need to stay on top of.
Is there a recommended mc file for running a Sendmail mail server?

I am also using procmail as well.

Thanks

If you have no compelling reason to switch from sendmail, stick with  
that.



I am wondering if qmail is thought to be better than sendmail.


My personal favorites in order are

 exim
 postfix
 sendmail
 carrier pigeons
 messages in bottles
 qmail
 smoke signals
 ...
 MS Exchange
 ...
 whatever system dogs use when they smell each others' excrement.
 ...
 Lotus Notes

You can't go wrong with the first three: exim, postfix, and sendmail.   
There are reasons why I have the preferences that I do, but they don't  
apply to you or your needs.  So unless you are having problems with  
sendmail, just stay with that.



Any suggestions on spam filters like spam-assassin?


There are many ways to integrate spam-assassin and sendmail, and they  
will all be in the ports system.  Look at mail/spamass-milter


Another approach (not using milters) is a spamassassin+procmail  
solution.  I prefer the milter as it allows you to reject mail early  
in the process.


Cheers,

No, sendmail is as good or better, especially in a situation such
as you describe.Some people believe that sendmail can be hard
to configure, and it is a little arcane to do it directly in the

exim is worth a look, it scales very well and is fairly easy to understand.
I also has a very powerful acl language for filtering and plugs directly

   First things first: if you're happy with Sendmail and your system works
   to your satisfaction, I'd leave it be.  Just watch your logs and keep an
   eye out for security patches.

A> I am wondering if qmail is thought to be better than sendmail.

   There are fanboys on all three sides of that question ("yes", "no", and
   "qmail bites, use this-other-MTA instead").  I switched from sendmail to
   qmail on a server because I had an odd corner case that qmail happened
   to handle just about perfectly.  I also botched a qmail install on my
   own workstation, didn't feel like finding out what I did wrong, and
   decided to install Postfix instead.

   I've had fine experiences with both qmail and Postfix.  If you're
   using a system that's a little under-powered, you might appreciate Dr.
   Bernstein's efforts to make qmail and its supporting tools *very* frugal
   with OS resources.  If you're used to the sendmail way of doing things,
   you'd probably be better off with Postfix.

   I like Dr. Bernstein's programming approach, but be prepared to spend
   time getting used to his way of setting up network daemons, etc.  It's
   internally consistent but *very* different.  It takes me 30-40 minutes
   to install all of the qmail stuff from source because I've done it at
   least 6 or 7 times; I could probably cut that in half if I didn't save
   build and installation outputs for my logs.  My first time took most of
   a weekend to figure out what was going on.

A> Any suggestions on spam filters like spam-assassin?

   I tried SA a few years ago, and it was a little heavy-weight for my
   filtering needs.  I use a simple Bayesian filter (ifile) trained on
   around 100,000 spams plus some procmail rules, and I get along fine.
   Your mileage will vary.  I saw some other comments:

>> Qmail is not, nor has it been, actively supported for years.

   Depends on what you mean by support.  The user community is very active;
   have a look at http://www.ornl.gov/lists/mailing-lists/qmail/ if you
   doubt it.  OTOH, said community can be a bit, um, brusque, but the Qmail
   Handbook and the "Life with Qmail" webpage filled in the blanks for me.

>> Qmail has a very limited set of features...

   It's intended to handle one problem well, which it does.  If you have
   some other requirements, http://www.qmail.org/ probably has a plugin
   that will do what you want.

   OK, now let's settle which text editor is best.

I personally prefer postfix too. It seems to be a relieable program, setting it 
up is easier then sendmail. It also integrates well with mailman (for the case 
you want to host mailing lists).

Some basic comparison:

Qmail is old. And there is no maintainer for qmail. How about Postfix?

I wouldn't ever recommend changing mail servers if you have a working
setup that you're satisfied with.  spamassassin works well with pretty
much any MTA, as far as I'm aware.

Qmail has a very limited set of features, it is simple efficient and 
pretty easy to setup, and has a track record as a secure alternative to 
sendmail.


Postfix I think is the flexible and popular alternative to sendmail. It 
supports most if not all of sendmail features and easily integrates with 
a number of filtering solutions as well as imap and ldap servers.

Qmail is not, nor has it been, actively supported for years. Personally,
I use Postfix. Is is far easier IMHO to configure that Sendmail and it
is actively supported. The developer regularly answers questions on the
Postfix forum.

Amavisd-new <http://www.ijs.si/software/amavisd/> works fine with
Postfix. You might want to stay away from
MailScanner <http://www.mailscanner.info/> though. The Postfix author
discourages its use and Postfix does not support it.

This is, of course, my own personal bias here but I wouldn't touch qmail 
with a ten foot pole. I know many have used it successfully and been happy 
with it. 

It is very easy to begin with a single domain for local delivery to 
configure sendmail as per the instructions in the Handbook. Postfix is 
designed to be a drop in replacement for Sendmail, and for a simple Sendmail 
already configured, Postfix will just take over and work when installed.

Additions such as MySQL for virtual domains and users, spamd, etc., can then 
be plugged in to the basic setup one at a time. There is a pretty fair 
amount of documentation in the Postfix world for such things.

If you are looking to change out Sendmail my vote would be Postfix as it is 
easier to build on and build up from the setup you're currently using. 

However, I'd like to point out if you have only one mail server you probably 
should do this on a second duplicate machine and then once it is proved to 
work properly swap them. There is a pretty good chance if you only have one 
mail server you're going to take it down while mucking about.

Re: Virus scanning for Exim mail server

[Olivier Nicole]

Hi,

Clamav, open source, in the ports, command line and daemon mode.

Kaspersky, commercial, command line and daemon mode for the mail
server package (something undocumented called aveserver and aveclient).

The advantage of a daemon scanner, when used in conjunction with a
mail server is that the scanner runs in the background and scans the
files that are submited to it, as the scanner is always running, it
does not take time loading the virus patterns every time, so there is
no start-up over head (few seconds) and the scan is very fast.

I think there are others, but these are the one I use. They both
integrate fine in amavisd-new (and I beleive amavisd-new works with
Exim).

Bests,

Olivier

I'll have to review this further. I'm not overly familiar with CARP (ie
I've never used it), nor PFSync.

My mentality for infrastructure gear (the balancers, not the servers) is
always "make each device connect to two different switches/routers, and
try to make it dynamic in a way that it fits into our OSPF/iBGP design,
so if necessary, we can move the entire thing to a different network
segment, and not have to renumber".

I'm getting a mental picture how I can have load balancing & failover
with the two devices, and network resiliency by having each balancer
connected to different network segments (between buildings over fibre if
I want).

Perfect...do your auth/acct db's generally reside on the same storage

altogether?

Ok. We have a Barracuda cluster hanging off of one of our Internet
facing edge routers, that filters then passes what it allows back into
the network, and to the servers. The only reason I don't aggregate all
of the mail systems together, is so that I can filter the spam as soon
as possible upon ingress to our network, instead of having it traverse
the core.

I do, and that would be fantastic! I'll draw up a diagram this afternoon
of what I envision. Where I'll need a bit of advice will likely be in
the details, as opposed to the design, especially if I migrate
completely away from our existing mail platform(s).

Not natively.  When we initially implemented this setup, ifstated wasn't
up to snuff, so we wrote some PERL scripts that make connections to the
required ports and, if no connection is established, pull the server
from the table and send us an alarm.  We also have scripts so that we
can pull servers out when we're doing maintenance.

They are behind the PF boxes.  We have other hooks in PF that we use to
block SPAM in PF, including Cloudmark and some custom stuff that looks
for multiple mails to non-existent addresses.  We also use the overload

That might be difficult because it's about 720 lines.  :-)  Here are
some highlights, though.

1) Our customers use mail.adhost.com for everything - SMTP, POP and
IMAP.  We use redirects in PF so that traffic coming in on the
associated ports goes to the appropriate servers.
2) We have our load-balanced DNS servers behind the same PF boxes so we
localize the tons of DNS queries related to mail.
3) We do a lot of our rejecting in PF, including Spamhaus, Cloudmark,
check scripts for Phishing, Porn and Viruses, as well as our own list of
"Nefarious" IP's culled from various sources.  When traffic matches
these originators, we send them to mail reject servers that send out a
550 message with the group name so we can find false positives more
quickly.
4) Because 3 does have false positives, we have a whitelist that we can
add to that will pass traffic to the mail servers before they match
against any of the tables in 3.
5) We use POP before SMTP, so once we authenticate a user to send, their
IP address is also added to an allow table.
6) The filter servers are load balanced to and from the mail servers so
we can take them in and out of their pool for maintenance.

If you have a particular scenario you're thinking about I could help you
with the rules to make it work.

Mike

Thanks Mike,

I'm interested to learn a little more about your setup. I was going to
take it off-list, but if you can provide some further details, it would
probably add long-term value to keep it here.

So, a couple of questions:

- can your PF load balancers 'sense' when one of the Postfix/Dovecot
units are down, or is this a manual change in config to prevent any
time-out conditions?

I like this load balancer idea. In my environment, it would be trivial
to set up a couple of them, throw Quagga on them, and integrate them
directly into our iBGP setup. On the other side, I could use VRRP or the
like to ensure redundancy from front to back.

- do the Postfix/Dovecot servers communicate with each other, or are
they simply stand-alone units that don't know/care that they have other
peers helping with the workload?

- are your filter servers in front of, or behind the load balancers
(iow, is all of your inbound email passed through the balancers, and
then filtered/processed/delivered in behind them)?

- how do all of the pieces communicate with the NAS...NFS?

- could you share a small snip of your PF config in relation to
load-balancing, so I can get a bit of a better understanding config-wise
on how that piece hangs together? (I've never used PF, only IFPW ;)

Thanks, and regards,

Steve

Hello Steve:

Another approach would be a cluster of Postfix servers and Dovecot
servers behind PF load balancers.  We have 3 "POP" servers (IMAP/POP), 9
Mail Servers, 2 Defer servers and 5 Filter servers that process over 20
million messages a day without a blip.  We can take individual servers
out of the pool for maintenance, etc.  Everything is fed to a set of
redundant NAS for the data storage and common configuration files.

This is *EXACTLY* what I was looking for!

The possibility of loosing an extremely small amount of data far
outweighs the possibility of a multi-hour outage where 3,000 users are
receiving "can't reach the POP3 server" errors.

Besides, our incoming SMTP gateway boxes cache all incoming email for 24
hours, and we can re-deliver any message to the back-end we wish during
that window.

I really try my best to design/implement all the systems I can like our
networks... multiple paths and extremely quick convergence. Being able
to take a box down to test/perform an upgrade, or during a failure
without client impact is well worth any initial large learning curve imho.

Thanks,

Steve

Now, that is a different kettle of fish.  This is a job for cyrus imap.
I suggest googling for 'cyrus murder' -- this is almost, but not quite,
a fully resilient mail store / IMAP system.  Your mail store is divided
into frontend IMAP protocol servers which handle user auth etc. and back-end
mail stores.  The protocol layer servers are fully resilient and you can
fail over a user session at will, but the mailstores don't quite get there:
mail is replicated across different stores, but actions modifying the mail
store are not transactional across all the mail stores. Or in other words,
you can lose a small amount of data if one of the mail stores goes bang at
precisely the wrong moment.  Even so, it will do better at keeping multiple
copies of a mailstore in synch than any locally scripted rsync setup.

Ok, I'm back up and rolling again.

Thanks Matthew, and the others who replied off-list for all of the feedback.

One thing that I forgot to ask in my original post was that of clustering.

In our production network, we have a cluster of perimeter MX's, and a
similar setup for our submission boxes (it's been a couple of years
since we've strictly enforced AUTH for all clients).

What I don't have, and have always wondered about, is live redundancy
for the IMAP/POP services.

I know that this would be a challenge to some degree considering the
high volume of data changes.

Perhaps a carp(4) setup between a couple of MDA's, where when the
primary is up, a constant rsync pushes the data to the backup. Or
perhaps a combination of rsync for manual changes, and a method to have
the primary write the emails to a local disk, and a network disk
simultaneously?

If anyone has a setup that has redundancy for their IMAP/POP services,
and a method to keep the changing data relatively up-to-date, I'd love
to hear about it.

Cheers,

Steve

with the setup I'm talking about, only 5% of the total volume currently
received is spam.  and that's a guestimate.

My point is that this is 5% coming through without using an anti-spam
product.  I was trying to get a feel for the software combination I spoke
about, how effective it was without anti-spam.

And then I said that the last 5% can be cleaned up by using anti-spam
software.


I won't elaborate to you any more.

Re: Stable Mail Server And Web Mail

[Jeff Dickens]

Another option:

Qmail and Dovecot.  Actually I have multiple servers running those at 
multiple sites.  For webmail, I have use squirrelmail and perdition, 
which is an imap proxy/multiplexer.  It makes the multiple dovecot 
systems look like one to the webmail system.  You could replace 
squirrelmail with any other imap-based webmail.


For anti-spam and anti-virus I use Postini.  A dollar a month per user.  
I send no mail except via Postini, and I accept no mail except from 
Postini, enforced by both qmail's tcprules and our cisco firewalls.  The 
combination is fast, safe and low-maintenance (but perhaps not your 
definition of cheap).


I've built this thing but only have a small contingent of users on it so 
far.. the rest are still on a external host.  Last week I set up mstone, 
(see sourceforge project) and have been loading it up to see where it 
creaks.  So far so good.

Only for single machine installs as I wouldn't recommend sqlite over NFS to 
share the database.
The idea was to have one machine (or a replicated cluster) with a database and 
several mail servers getting their information from there. It's less about 
performance, more about a preference of how you want to manage your 
information.

There are many factors that could be contributing to the speed of MySQL.
For starters, what version are you employing? I believe
"databases/mysql60-server" is the latest version in the ports tree. Have
you tried using:

BUILD_OPTIMIZED=yes
BUILD_STATIC=yes

Their use could improve the speed of MySQL.

There are other options in the Makefile. Unfortunately, you have to set
them manually.

Depends on your usage. I'd say for SMTP table lookups, MySQL can out perform
PostgreSQL, unless one uses persistent connections (postfix proxy-map to be on

lower overhead then for PostgreSQL.

Depends on your usage. I'd say for SMTP table lookups, MySQL can out perform 
PostgreSQL, unless one uses persistent connections (postfix proxy-map to be on 
topic). The reason for this is that the connection start up for MySQL has 
lower overhead then for PostgreSQL. So typically with small tables (lookup 
maps for transport and users are generally not in the order of millions) and 
lots of connections MySQL could win. On the other hand, PostgreSQL scales 
better, especially now that the Sysv IPC shared memory limit in FreeBSD has 
been fixed. [1]

The reason for my original remark is that Oracle now acquired SAP DB, MySQL 
and Berkeley DB, so the best scenario I can see is that they improve the 
underused Berkeley DB table handler for MySQL and leave the rest in-tact, but 
I more expect them to phase out MySQL or grow it with Oracle features, neither 
of which I personally consider a good thing.

Just thought I should make a couple comments, it's not a message to change
or correct Mel's message but rather just a idea on a possible solution I
have deployed and would like input and experience/results relayed to me.


Put whatever MTA you want, I use postfix primarily.  sendmail would work
too, but I don't know exim or qmail.

Install OpenBSD's spamd (that works with PF, and ipfw support is early, but
there) on the host to block the (at last count) ~460k hosts and subnets that
are known spammers so your MTA doesn't even have to mess with it.
Include DNS Blacklisting support with your MTA.  These are the servers that
have mistakenly sent out a spam and gotten caught.  DNSBL will report to the
client that it's being blocked and how to remove it.


I'd love to hear success stories with this.  Both pieces together work very
well, and I am still working on seeing if any spam does come through.  If
spam does come through, a product like dspam or spamassassin could finish
off the job.


I don't have a live domain, so I can give directions if anybody's

I ask please - for those who are interested in trying this, to give me the

Sure. And they will accept mail for everything in the database, you will have 
no good routing as any given setting applies to any given postfix 
installation, unless you maintain internal DNS and transport maps locally and 
very carefully.
So my own database has a 'servers' table and transport / relay are 
applied per server. This way an incoming mailhub accepting for all domains can 
get transport info from the same database and multiple transport maps can be 
applied for the same domain, pending the role of the server in the mail 
network that requests the info. Postfix (and dovecot) maps simply have a WHERE 
me='mailhub.example.com' clause.

I don't think PHP itself is buggy, in fact I think badly written C

It all depends who write programs.

I don't think PHP itself is buggy, in fact I think badly written C
programs are responsible for far more lossage.

Though you're right about resource-hunger.

What i use is:

spamassassin as antispam, someone already pointed that dspam is faster i
must check it. Anyway properly configured spamassassin isn't that bad.

sqwebmail for webmail. it's highest performance and easiest to configure
webmail i've tested. It's fortunately not PHP based, it's written in C.

Option c and do not understand.

You can use a centralized database and let as many postfix, dovecot servers 
talk to that database as you want, or am i seeing this wrong.

It's a detailed how-to but consider the following:
a) With Oracle acquiring Sun, one should move to PostgreSQL where ever 
possible.
b) Spam Assassin is a resource hog, use mail/dspam.
c) While postfix-admin is ok for one box setup, it doesn't scale at all - 
you'll have to install it for every physical machine to manage that specific 
database for that box. I know of no alternatives, hence I'm rolling my own.

Anybody to know a good Stable Mail Server and Web Mail


Postfix
Cyrus
(+possible Postgres if database is needed)
Squirrel, IMP...

One can build very decent BSD or like licensed mail server, except the 
webmail part. Every available webmail package I've found are under 
GPL.

I love the following combo:

Exim as MTA
Dovecot for POP3/POP3S/IMAP/IMAPS
Vexim (http://silverwraith.com/vexim) for web based management
MySQL or PostgreSQL database
Squirrelmail for webmail with vlogin plugin for multihosting.

A good combination for webmail is:

Postfix as MTA
Dovecot as IMAP / POP3 server
Postfixadmin for webbased management.
Mysql or postgresql for the database.
and a webmail client.
This can be roundcube, squirrelmail, imp (from Horde) and so on.
