Qmail + vpopmail + qmail admin problem

[Dave Lewis]

ok.. I got it all installed.. everything seems to be running.. except..


all my virtual domains cannot check mail.. pop3 won't authenticate.  my 
default domain with
local users can check pop3 no problem.  Mail is being delivered to the 
approperite /domain/xyz.com/user/Maildir/new
though


Also I can't seem to get my local domain to work as a virutal domain.. i.e. 
no local domains at all


on top of all this. Qmailadmin worked great... and now only gives me 
invalid login for any of my virtual
domains.. I even tried reinstalling qmailadmin and creating a new virtual 
domain.. same thing..


Please tell me that someone has seen this before and can help ??? I've been 
banging my head up
against a wall for about a week now.. and frankly it's getting a little sore :)


Thanks in advance for any help.

Re: User Masquerading...I think that's what I need?

[Konstantin Rozinov]

Hey again...

An addition to my previous question:

I also want to be able to add this to /etc/aliases:

billing: ukon, joe
info: ukon, john

So that when I (ukon) or joe responds to an email it will be from
[EMAIL PROTECTED] and same thing for [EMAIL PROTECTED] (for ukon and
john).  I realize i can use the environment varibles from the FAQ:

Add MAILHOST=af.mil, MAILUSER=boss, and MAILNAME='The Boss' to your
environment.

But, what if I have the need for multiple user masqueradings (like for ukon
and joe and john)?

Please advise.
Will Summarize.
Thanks a lot.

This is best done with your mail user agent (MUA) IMHO -- user
masquerade is trivial with a decent mail client. Mutt does this quite
easily, and I'm sure that any decent MUA can do this to -- right down to
the envelope-sender matching the masqueraded from. Indeed, this is one
of my qualifiers for a decent MUA...

User Masquerading...I think that's what I need?

[Konstantin Rozinov]

Hi folks,

I am new to the list and to qmail.  I just installed it using the Life
with Qmail guide and the Qmail HOWTO.  I also checked up on some of the
man pages.  So everything seems to work fine so far.

But I have this question:

I currently have fast-forward package installed so I am using
/etc/aliases and I have this in it:

support: ukon, joe, john, mxp

note: all these are local user accounts.

So, is it possible to have some user on the internet ([EMAIL PROTECTED])
send an email to [EMAIL PROTECTED] and when I (ukon) or joe or john
or mxp answer him (userX), the From: line will have this:
[EMAIL PROTECTED], instead of
[EMAIL PROTECTED] or [EMAIL PROTECTED], etc... I don't want to reveal
any usernames or private emails.  Is that possible with qmail?  I have
seen it being used with many large companies and I want to set it up
here too :-).

Can this be done WITHOUT creating a "support" user account?

Thanks a Lot!

Mail-Proxy. Ould have you write the mini-howto?

[Alejandro Fernandez]

I read January thread about Ould wanted to write a mini-howto about how
to configure qmail to act as a mail-proxy.

Ould, I wonder if you write this howto or anybody did it.

If so, please let me know.

Forwarding Problem: Solved!

[Philip Mak]

I found out two things:

(1) compiling a perl script every time an e-mail message arrives is
quite inefficient, but connecting to the database is okay
(2) I had a mail infinite loop

#1 was fixed by rewriting my .qmail-default script in C instead of perl.
It does almost exactly the same thing, except:

#2 was fixed by calling /var/qmail/bin/forward instead of
/usr/bin/sendmail to forward the message. forward adds a "Delivered-To:"
header that does mail loop checking, while sendmail doesn't.

It turns out that I had [EMAIL PROTECTED] who had set his e-mail
address forward to "baduser", so it kept looping back to himself. I did
have a check in my perl script not to forward to anything @mydomain.com,
but I didn't check for e-mail addresses that had no @ sign!

So, the perl script wasn't really responsible for jacking my system load
average up to 10; the baduser was. Upon disabling the baduser's forward,
the load average with the perl script went down to 1.5.

The load average with the C script is 0.10. Yay! ^___^

That won't work exactly as is, since you need lynx to send the contents of
standard input to the PHP script as POST data. "man lynx" shows the
following option:

   -post_data
  send  form  data  from  stdin using POST method and
  dump results.

So try putting -post_data in the lynx command.

A more correct way of doing this would be to run php from the command
line. Try typing locate php | grep "/php$" to see if a PHP executable is
available on your system. If not, you can compile one by downloading PHP
from php.net, doing "./configure" (don't include any options in
./configure), then "make" (don't do "make install"), and just copy the
"php" executable that it creates to whereever you need it.

If you go with the PHP executable, you would put in your .qmail file:

|/path/to/php -q /path/to/script.php

(-q tells it not to send HTML headers.)

Program Delivery to PHP Script

[PHP Webmaster]

Hello,

I am trying to implement a .qmail file so that
whenever someone sends a message to
[EMAIL PROTECTED]

the .qmail makes a program delivery to a PHP script at
http://www.mydomain.com/parser.php which then stores
the message in a database. The PHP installation is as
an Apache module so I think I might have to use Lynx.

So here is something I've come up with:

|/usr/bin/lynx -source
"http://mydomain.com/parser.php";

Would something like this work? Or is there a better
and more correct way of doing something like this?

Thanks!

Re: stunnel/POP3 hanging ??

[Lordy]

Hi David,

i had a very similar problem with stunnel and POP3 on my mail server.

I installed and run stunnel pretty much the same way you did and tried to 
retrieve
mail with Eudora 5.1 which failed (unfortunately you didn't mention your Eudora
error message so I can't tell if it's the same one).

When I tried to connect with Outlook Express everything works just fine.

I guess this might be a problem in the SSL implementation in Eudora but I'm
not to sure about that. I've tried to find more information on SSL on the 
Qualcomm
pages but they don't provide anything there.

Sorry that I can not help you but let me know if find out anything about 
this issue.

Regards,
Lordy

To move all your domains you also need the entries
from /var/qmail/control/rcpthosts /var/qmail/control/morercpthosts
/var/qmail/control/virtualdomains and /var/qmail/users/assign

Also make sure the vpopmail uid/gid is the same on both machines,
otherwise you will need to change the uid/gid values in 
/var/qmail/users/assign

This doesn't work with qmail-queue. I have yet to find anyway to get a
message either returned to the sending server or to the logs. I've tried
printing to standard out and standard error.

Re: SMTP help...

[Peter]

Found the problem...  It was in fact 'slow', although so slow I had to wait
almost 10 minutes for it to come up...  a lot longer than I usually would
for dnslookups.

For others searching the archives on similar problems, my tcpserver was
already running with the -H option...  It turned out to be the localhost
lookup that was killing me, not the remote lookup.  It selected the
servers -internal- IP address, 192.168.1.1 to lookup instead of the external
IP address.  Naturally this did not resolve.  Anyway, the problem was solved
by specifying tcpserver -l 0  option.

Thanks for the help,
Peter

I'll bet it will appear eventually. Give it a minute or so.

If it appears after a minute, then your question is the number one FAQ on this

SMTP help...

[Peter]

I suspect this problem is an easy one to fix, but despite going through the
docs I still don't know exactly what's happening, so any suggestions are
appreciated.

1)  I have qmail 1.03 configured as per instructions available here on my
debian GNU/Linux box:
http://www.flounder.net/qmail/qmail-howto.html

2)  Receiving messages works just fine.

3)  Sending messages from my local network 192.168.1.x (this server is
acting as a masquerade server) using this smtp server /used/ to work just
fine.  This is no longer the case.


The problem:
When I telnet to my smtp server from the localhost I see:
---
220 cr134008-a.slnt1.on.wave.home.com ESMTP
---
Fine and dandy.  Sending mail from localhost seems to work fine.

However, when I telnet in from my desktop machine (192.168.1.2) it accepts
my connection, and -nothing- appears. The server will not give any
acknowledgements.

So I check my /etc/tcp.smtp:
127.0.0.1:allow,RELAYCLIENT=""
192.168.1.:allow,RELAYCLIENT=""
:allow

I recompile it just to make sure:
tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp

I restart:
/etc/init.d/svscan stop
killall tcpserver
/etc/init.d/svscan start

And I get the same problem.

In the logs I get:
/var/log/qmail/qmail-smtp:
@40003b631ddf1226723c tcpserver: status: 1/40
@40003b631ddf123c7ec4 tcpserver: pid 5169 from 192.168.1.2

Let me know if you think sending my qmail control files would help.  I
thought at first this was an access control issue with tcpserver but now I'm
not so sure.  I am wondering if it has to do with the fact that qmail can't
do a dns lookup on 192.168.1.2.  Anyway, my qmail 'me' control file contains
the name my external IP address resolves to.  My 'rcpthosts' includes
localhost, the name my external IP address resolves to and a couple other
domains I own.  My 'locals' file contains 'localhost' and the name my
external IP address resolves to.  My virtualdomains control file contains
names/usernames of my virtual domains.

Any suggestions?  Where is the problem most likely to reside?

Thanks in advance,
Peter

stunnel/POP3 hanging ??

[David Vrona]

Hi all,

I've been running a very stable RedHat installation with qmail for some 
time now.

Recently I've tried to install the stunnel wrapper on POP3.

I believe I've done everything as I should but clients cannot successfully 
retrieve e-mail.  It appears that something is hanging during the 
process.  The client program (Eudora) appears to be stuck trying to get e-mail.

On the server side I have the following in the log:

Jul 28 16:39:13 ikauni stunnel[5270]: Using 'qmail-popup' as tcpwrapper 
service name
Jul 28 16:39:13 ikauni stunnel[5270]: stunnel 3.16 on i686-pc-linux-gnu 
PTHREAD+LIBWRAP
Jul 28 16:39:13 ikauni stunnel[5270]: qmail-popup connected from 
192.168.1.3:1307
Jul 28 16:40:16 ikauni stunnel[5270]: SSL_accept: Peer suddenly disconnected

The last line occurs when I force the client to stop trying.

Here is my invocation of stunnel:

#!/bin/sh
exec /usr/local/bin/softlimit -m 300 \
/usr/local/bin/tcpserver -v -likauni.vrona.com -H -R 0 pop3 \
/usr/local/sbin/stunnel -p /etc/stunnel.pem \
-l /var/qmail/bin/qmail-popup -- qmail-popup ikauni.vrona.com \
/bin/checkpassword /usr/sbin/relay-ctrl-allow /var/qmail/bin/qmail-pop3d 
Maildir 2>&1

I wonder if anyone has run into this situation?  I wish I could provide 
more information about what is going on.  I guess they are ways to trace 
this but I don't know how to do it.

Thanks for any ideas.

Dave

Not really.  The closest you can really come to redundancy would be to
put in MX records for all the servers with differing priorities (the one
where mail is stored should be marked with the lowest number) and put
the domain just into the control/rcpthosts file on the other two and not
into the control/locals file.  The reason you cannot have a seamless
uptime over three different servers spread across the US is because
clients would somehow have to be able to connect to a server where the
mail is stored.  Unless you can figure out a way to get the mail servers
to synchronize the queue over the 'net, you're out of luck.

BTW, tell your MUA to wrap your messages at 72 characters, it quotes
better then. ^ ^

Yep.

The way to do this optimally is to have a program that does the lookup
and then execs /var/qmail/bin/forward (or possibly qmail-queue for a
minor performance gain).

Oh, so you're saying if e.g. on mydomain.com I have the file .qmail-pmak
that says:

Yes. This program could then just talk to /var/qmail/bin/qmail-queue itself,
or talk to /var/qmail/bin/forward.

I have no such proposal. I just feel that with some changes to the
queueing structure, this might be feasible. On a 100mbyte mail, this
saves reading+writing 100mbyte when a mail is forwarded.

Is it really that complicated to get the forwarding alias from a program?
I'm thinking---at the moment when qmail is reading the .qmail-default
file, it can encounter:

&[EMAIL PROTECTED]

At this point, it has the capability of specifying a local or remote
e-mail address to forward the message to. Doesn't it?

So it should also be able to easily run an external program at this point
to determine the e-mail address to forward to.

I am not familiar with the internals of qmail, but from what I have seen,
this would make sense.

About message size...

[Ertan Yusufoglu]

Hi,
 
I have installed qmail with vpopmail and added some 
virtual e-mails
with vpopmail. Also I set the quotas. Quotas 
sometimes don't work.
Because vpopmail use the message size which is 
specified in 
mail name (I use Maildir format). Like this 
:
 
996173026.28450.ns,S=193633
 
But I have realized that not always thss message 
size is specified in
then file name. So vpopmail can't calculate the 
real size of messages.
Firstly I thought that it is a problem with 
vpopmail's deliver porgram but I have
a few system accounts in which mails are delivered 
directly by qmail. I saw file names
which don't contain size expression.
So why qmail sometimes adds "S=" and sometime 
doesn't?
 
Thanks in advance

We have a similar script.  Watch a mailing list hit and the load average
goes way up.  We only use it where WYSIWYG changes to forwarding addresses
are required; the per email compilation is way out of line.

I've always assumed the "right" way would be some sort of UNIX socket 
connection with a persistent daemon and a local database server + 
backup cache or exit 111.  I wonder if one could not put a filter in 
front of some app-server to do just that

If changes happen infrequently relative to time to rebuild the cdb file, 
then doing that for each change sounds like it would be simplest AND most 
efficient.  The only complexity would be triggering that rebuild on db 
change.  Not so easy with mySQL but maybe your mechanism for updating 
could do it.

At least it solves MY problem; that will work nicely for us.  :-)

Unless the destination address happens to be in a virtual domain on the

You may want to look at dteq (www.dataloss.nl/software/dteq/) in that

However, using `` allows you no way to detect errors in the query. If

About 2 a second, that's not huge, but it's starting to get busy when
you have to invoke multiple programs and establish a socket each time

No. quite the opposite if anything. Think of concurrencylocal as a
peak load that you want qmail to impose on your database - or your
local file system for that matter.

Do you really want to have more than 10 concurrent connections to your
database? Better to keep that number safely within the capabilities of
your system.

I suspect that 10 is a good starting point for your delivery rates and
it's much better to have an occassional local delivery delayed than to
grind your database into dust.

Ug. That's even harder and it saves less than half of your queuing
costs!

That approach means that the message changes from a local to a remote
delivery - the queue structure does not lend itself to making this
change easily without incurring most of the cost of a queue
injection. It also likely that the length of the recipient address
will change - again the queue structure is poorly suited to this for
multiple recipient emails as recipients are stored as a series of \0
terminated strings.

It'll be interesting to see how you propose to atomically make such
queue changes while incurring a worthwhile queueing cost saving.

A 'select * from ...' followed by a fastforward cdb rebuild should
pose no interesting load when executed, say, every 5 minutes,
depending on volume. For 24.000 aliases (just assuming for now that
you have about as much aliases as users), every minute can be
feasible.

You are missing the point. We are just saying that a program invoked
by qmail-local should have a way to communicate back to qmail 'change
the address to blah', instead of having to reinject it. This would
then still happen for every recipient like it does now.

Maintaining a persistent connection across multiple local deliveries
is possible with some skull-hackery and a cooperating peer process,
but it's not easy, it's not possible using flock and it does raise the
issue of multiple deliveries using the same connection at the same
instant.

Tell us more about the deliveries? How many per hour, what is your
concurrencylocal? Are the deliveries keeping up? An unadulterated
snapshot of your qmail log would tell us a lot.

At this stage, periodic rebuilding of a fastforward file sure sounds
easiest - perhaps triggered by database changes.

The qmail architecture does not lend itself well to this though does
it? qmail-remote is the only code that knows how to remotely deliver a
message and qmail-smtpd would have to be (extensively) modified to
call that instead of qmail-queue.

It would have been a cute touch if DjB had made the interface to
qmail-remote the same as qmail-queue. In fact, one wonders whether all
the inter-program delivery of mail in qmail should use some sort of
common protocol such as that used by qmail-remote. Better yet would be
to universally use QMTP/QMQP between programs.

Anyway, even overcoming the interface obstacles, you have the nasty
problem of inbound multiple recipients to deal with. qmail-remote only
handles multiple recipients if they all happen to be going to the same
domain.

You could simply punt to qmail-queue of course if there is more than
one recipient, but now it's starting to get messy as your delivery
paths will be substantially different for the same recipient simply
depending on whether they are part of an inbound multiple recipient
mail or not.

You can't store persistent database connection handles in flock'd
files.

There are two ways to persistent database connections:
- do your stuff from within qmail (probably not the right spot)
- have your perl/C program connect to a daemon that has a couple of
  persistent connections

But I don't think this will help anything - most of your time is
probably spent compiling perl.

My recommendation is to use fastforward.

24000 total users on a Pentium III 850MHz with 768 MB of RAM (not sure
how many are active though...at least a couple thousand).

I currently use .qmail-default to run a perl script which connects to a
MySQL database, performs a lookup on the alias, then opens a pipe to
sendmail to deliver the message.

Upon activating this system, the load average of the machine has increased
from 1-2 to 10! I suspect most of the time is being spent compiling the
perl script and connecting to the MySQL database, though. If I switch to
fastforward (or if I rewrite the script in C, and use a persistent
database connection handle somehow, maybe by storing it in an flock'd
file) maybe the load average will drop back down to normal.

That's not what he means. This still reads the message and reinjects
it. His proposal (which I have been pondering about for months already

In other words he doesn't want each mail to go thru the queue twice as
your solution implies.

To answer Philip's question: Yes, that overhead is unavailable as
there is no standard qmail solution for redirecting mail without it
going thru the queue at least once.

Having said that your concern about overhead may be misplaced. What
sort of volume are you expecting on what sort of system?

Oh, I see now; fastforward is a program that I specify to be called in
.qmail-default. I thought it was a patch to be applied to qmail.

So it would still have the overhead of having to read a message from
qmail, and then write that message back to qmail. That overhead would be
unavoidable if I'm doing program delivery, I guess.

I wonder if in the future, they'll make an "alias delivery" option in
qmail; that is, it calls an external program, but instead of sending the
entire message to the program, it just sends the "RCPT TO:" address to the
program and the program returns to it which mailbox(es) should be
delivered to. Then again, this could turn out to be an ugly piece of
'feature creep'.

That turns rblsmtpd from an IP-level ACL enforcer to a mail proxy, so
it's more like a brand-new program.  You're much better off running a
proper filtering SMTP proxy for this purpose.

I'd be more worried about speed of delivery than speed of DB regeneration.
Note that it's still a program delivery, albeit done through a more
efficient program than your existing perlDB script.

As an aside, has anyone done any performance comparisons between
fastforward and .qmail-forwarding for large numbers of aliases (>10,000)?

fastforward is traditionally invoked in ~alias/.qmail-default, so unless
you have some other delivery instructions already in that file, everything
else should still work.

custom message during sending mail via my smtp server? current state
is:
i wrote custom script which substitute qmail-queue, it unpack received
message, starting antivirus and if message infected anyone, return
code '111' i.e. temporary problem, and deny message relay via server.
but, user cannot understand reason of relay-deny. so, server must
return custom error message to sender. how i can made it?

Yups. Got one too.

Yes.

Apparently. I have mailed [EMAIL PROTECTED] about this, but have
received no reply (yet).

Yes, they will work. fastforward will just sit in .qmail-default and
handle anything that's not being handled by their own .qmail file.

Anti Virus Software Update

[Mike Hodson]

Hey again.

Over the past few hours ive been configuring AmAViS-perl 11 for my qmail
setup.  After using a wrapper for suid (my suidperl complained, stinking
thing) I was able to make it work without a hitch. Infact, this mail is
being scanned on its way out.

If anyone else is contemplating a virus scanner, Id reccommend this, and
if you need any help with it, let me know. Ive gone through atleast 20
different individual problems on this install =)

Fastforward question (was Re: Mail Forwarding Service)

Hmm, looks like it could work. The "Speed tests" section of
http://cr.yp.to/fastforward.html says that it takes only 6 seconds to
regenerate an alias db with 5 entries. I could run a cron job every
two hours to regenerate the cdb.

My question about fastforward is: Will my existing .qmail-* files stop
working? If so, how can I make the ezmlm aliases still work? e.g. one of
my .qmail files for posting to an announcement list says:

|egrep -i "^From:.*([EMAIL PROTECTED])" || (echo "Permission denied."; exit 100)
|/usr/local/bin/ezmlm/ezmlm-reject
|/usr/local/bin/ezmlm/ezmlm-send '/home/ptscb/lists/buildreferrals'
|/usr/local/bin/ezmlm/ezmlm-warn '/home/ptscb/lists/buildreferrals' || exit 0

I don't think this would work in /etc/aliases, which is supposed to be one
entry per line.

Use fastforward - http://cr.yp.to/fastforward.html

Periodically dump the relevant parts of your MySQL database into the
cdb that fastforward uses.

Yes.

Certainly much less than running a perl+DB script on every incoming
message.  If you're really worried about filesystem performance (almost no
one is), go with qmail-ldap instead (see www.qmail.org for the URL).

Unless you're in a habit of editing your DB directly, just add
the necessary (but trivial) instructions in your DB scripts to
update/create/delete .qmail-* accordingly.

That depends on your filesystem.   I've just learned of ReiserFS, isn't 
this the kind of thing that it's good at?

How often do you expect it to change, and what triggers the 
change?  Write a cron job that updates the .qmail files periodically 
with the information in the database.

Better yet, update the .qmail file at the same time you update the 
database.

There is at least one mysql/qmail integration package floating around, 
have you looked at any of those?

You're going to have a very hard time making this tiny and fast, which 
is what it needs to be.  For every message, you're firing up the perl 
interpeter, connecting to the database, parsing a statement, executing, 
and cleaning up the whole mess.  All of these things are expensive.

You might be able to improve things be writing a daemon (in perl if 
you'd like) that spins in the background and takes connections from the 
various .qmail files.  That will at least eliminate the 
once-per-message startup, and you could probably get it to share 
database handles.

That's a lot of work, and a lot of shit to break.

cheers,
Todd
