Avoid recursive table lookup

[Arnaud JAYET]

Hello,

i'm trying to set up a Vacation Mail Responder using postfix and special 
transport + PERL script.


i want to let users choose between :
case 1 : automatic vacation responding and not delivrering the original 
message (message is lost)
case 2 : automatic vacation responding and delivrering original message 
in their mailbox


note : i'm using a MySQL lookup for storing users vacation parameters 
but i have got the same problem with standard db lookup



My configuration


transport :
autoreply.domain.tld:autoreply


master.cf :

autoreply   unix-   n   n   -   -   pipe
  flags=Oqu user=nobody argv=/usr/local/bin/vacation.pl $sender $recipient

main.cf :

virtual_alias_maps =
hash:/etc/postfix/vir_vacation,
...
...
...

in vir_vacation i can have

case 1 :
u...@domain.tld u...@autoreply.domain.tld

case 2:
u...@domain.tld u...@autoreply.domain.tld,u...@domain.tld


in case 1, all is fine, original sender receives the automatic mail

but in case 2, PERL script is called twice (but the message is well 
delivered in user's mailbox) and so there is 2 automatic mail sent to 
original sender


how can avoid this "recursive" lookup in the table and sending automatic 
vacation message twice ?



Note : I found a solution for case 2 using another transport to deliver 
 the original mail and sending a vacation mail :


transport :
autoreply.domain.tld:autoreply
deli...@domain.tld:  relay:[imapserver.domain.tld]

case 2:
u...@domain.tld u...@autoreply.domain.tld,u...@deliver.domain.tld

on the imap server i have a canonical regexp to rewrite
u...@deliver.domain.tld --> u...@domain.tld

/^(.*)@deliver.domain.tld/   $...@domain.tld


but if i could avoid this ("heavy" ?) solution

Not sure regarding the Ironport, but I imagine it is just the same as
the Barracuda. The 'Reputation' is just an in-house rbl list and Yes,
Postfix does these very well indeed. Here I am making use of a few;

smtpd_recipient_restrictions =
...
reject_rbl_client zen.spamhaus.org
reject_rbl_client pbl.spamhaus.org
reject_rbl_client dnsbl.sorbs.net
reject_rbl_client b.barracudacentral.org

Apart from a pretty GUI, you can achieve virtually all of what an
Ironport or Barracuda does with Open Source *free* software. That's all
those 'appliances' are. Open Source cobbled together and sold to you.

My money would say - don't waste your cash on the Ironport (and
certainly don't spend a cent on a Barracuda). 

handling non MX entry domains

[truth_seeker_3535]

Dear Pros,

I am using postfix-2.3.3-2 on CentOS 5.2. 

a. There is a valid domain called example.com.ex with a valid MX entry
b. There is another domain called example.com withour a MX entry (both can 
be for same company or for different)

Now when a user tries to send mail to u...@example.com.ex, its is successfully 
delivered.

But when a user tries to send mail to u...@example.com, even though it cant 
find the valid MX entry for this, still it is trying to send mail to the IP 
address which is resolved from example.com  because of this the sender is not 
getting any error message and this mail is there in the mailq for a long time. 
("connection refused" error message can be seen in the output of 'mailq' 
command).

The sender think that, the mail is successfully delivered, eventhough the 
reality is vice versa.

1. Is there any way to configure in postfix that, if he didnt find MX record 
for a domain even after (say 3 or 5 times) then postfix has to stop the 
processing of that mail, and send a error message indicating the MX problem to 
the sender.

2. Is there any way, to notify the sender the status of the message (other than 
sent). For eg; 
 a.. if a message sent successfully no need of any report or notification.
 b. if a message is in deferred queue, it should send a notification to user 
that, this is in deferred queue due to so and so issue (may be MX, may be 
network timeout, etc) and will try to deliver it in a later time.


Any guidance is really appreciated ;

From 'man 5 postconf':

delay_warning_time (default: 0h)
   The time after which the sender receives the message headers of mail 
that is still queued.

   To enable this feature, specify a non-zero time value (an integral 
value plus an optional one-letter suffix that specifies the time unit).

   Time units: s (seconds), m (minutes), h (hours), d (days), w (weeks).  
The default time unit is h (hours).

Cryptic message for end users

[Rocco Scappatura]

Hello,

I have a postoffice system based on
Postfix+MySQL+Courier-IMAP+Courier-authlib+Maildrop.

I have enable quota checking with maildrop.

When quota is overcame then Postfix get a permanent error by maildrop
and generates a bounce with the following informations:



The message is 'as-is' reported by the MTA of the sender, to the sender.

This message is clearly too technical for end user which claim that mail
system has a fault!

Could I configure Postfix so that the message generated by Postfix when
the quota is exceeded, is easier to understand by end user? Or is a
matter of maildrop?

Thanks,

rocsca

The latter. It even says so:

maildirmake: /pathto/user/: File exists 
maildrop: maildir over quota.

Restrict from domain based on sasl auth id

[ram]

We provide relay services for our clients. 

The clients mail-servers connect to our postfix servers , authenticate
using a client-accountid and send the messages. 

I would like to restrict the from domains for every client.(Mainly to
prevent inadvertent spam outbreaks) 

Can I use smtplogin maps to allow  only a list of enumerated
from-domains in the envelope senders


eg

/etc/postfix/smtploginmaps

accountid1  *...@domain1.com,*...@domain2.com
accountid2  *...@domain3.com

I assume you're thinking of non-local delivery

queue_run_delay = 300s
maximal_backoff_time = 4000s
minimal_backoff_time = 300s

The queue is scanned every 300s, initial minimal backoff is 300s,
maximum backoff is 4000s, with every unsuccessful retry the timespan
between to attempts is increased.

What you mean precisely? How I can find the mistake?

Here my maildrop conf file:

log "test -d $HOME$DEFAULT"
`test -d $HOME$DEFAULT`
if ($RETURNCODE != 0)
{
log "mkdir -p $HOME$DEFAULT"
`mkdir -p $HOME$DEFAULT`

Re: Reputation based filtering...

Check out RepuScore: http:.//isr.uncc.edu/RepuScore. The spamassassin
plugin we designed computes reputation and stores them in a database.
We have not closed the 'loop' using reputation to classify emails,
yet. But, you can use it as a part of spamassassin scoring.

Thanks for the reply...

but i didnt get any explanation on how it sends to a domain which he didnt find

delay_warning_time will notify the current status to the user? or it will warn

If no MX record is found, the A record is used.

If example.com doesn't have a MX record, it will use the A record of 
example.com (if it exists).

It tells the message has not been delivered yet, and that the system will 
continue to try (until max queue lifetime is reached).

Stop accepting mails from clients but process the mails which is already in the queue???

[Truth Seeker]

Dear Pros,

how can i stop accepting mails on postfix server from all my clients but at the 
same time, i want to postfix to complete the tasks in the queue.

For eg; if i want to do some maintenance work on the system, i want to first 
stop accepting mails in my mails server from the clients. Then i want to wait 
for the server to complete the processing in the queue (which he is already 
accepted, then after that i want to shutdown the postfix service completely 
inorder to carry out my maintenance task

Re: handling non MX entry domains

[Truth Seeker]

Really thanks to ruben and terry...

Let me set this setting...

by the way, i am curious to know, if i want to delete a particular mail from 
the queue (may be in active or in deferred) how can we do that.

an example like mail message id 8AD5TYU is in deferred and i want to delete it, 
how can i do that (if i delete, this manually, any problem for the system ?) 
and if i delete this with a command, will the postfix send a notification to 
the user?

another example mail message id 6FG23DB is in active queue and i want to delete 
it. how can i do that (by notification to the user and also another way without 
notifying the user) 
what will happen if i delete the mail message by rm command from the active 
queue?

In the /etc/postfix/master.cf file change the line smtp... to 127.0.0.1:smtp

postsuper -d QUEUE_ID

For more info: man postsuper

you can get the queue ID from the message or postqueue -p

Never delete things manually from any active queue.

You can delete queued messages with the above command, however in any case,
there will be no user notification for the sender or intended recipient.

Never delete things manually from any active queue. I doubt it would work
anyway, from the ACTIVE queue, but would absolutely not recommend trying it.
Postfix doesn't expect files to be ripped away while being processed.

AFAIK you can do what you want with anything in the HOLD queue.

Well, it sill stop postfix from listening to anything other then the localhost 
for submissions therefore preventing external (to the machine) submissions.

When you are done, just remove 127.0.0.1: from in front of the smtp statement.

While I remove line cousing error 2.

rocsca

what is the meaning???

[Truth Seeker]

Dear Pros,

now to do flushing for a particular domain, i am trying to configure fast flush 
service. in the documentation i found the following line, which i am confused.

could anyone explain this further

As mentioned in the introduction, the mail is delivered by connecting to the 
customer's SMTP server; it is not sent over the connection that was used to 
send the ETRN command. 

i feel like they are mentioning about two connection? 
i didnt understand which are these two connections? 
then i feel like whenever we are sending a mail to a domain, its usual that it 
will try to connect to that particular mail server to deliver it. in such a 
case, why here they mentioned about 2 connections???






  

RE: Stop accepting mails from clients but process the mails which is already in the queue???

[Truth Seeker]

First i tried to do this by looking in to main.cf. but i didnt find any line 
regarding listening on my ip. rather i found the declaration about mynetworks 
which i changed to 127.0.0.0/8. then i tried to connect to port 25 by telnet 
from other machine, it was connecting. so i reverted the changes and then tried 
the Ralf's way.

that is, i disabled the smtp line (by comment) master.cf and then postfix 
reload. which completely disables the smtp. 

once again thanks for the help

There is no need to manual delete mail from the queue that way.

When mail can't be delivered, Postfix will return it to the sender
after $maximal_queue_life_time.

with transport, i do: master.cf:
smtp_teste   unix  -   -   n   -   -   smtp  -o
myhostname=mx.test.com

and call it based/destination in /etc/transport_maps.

thera one way to do it with sender based ?

message_size_limit

[Simon Schelkshorn]

Hi there,

I added a second listener in my master.cf. For this listener I added 
the option message_size_limit=2048 to increase the maximum size 
for emails sent via this additional listener.

192.168.xxx.xxx:25   inetn   -   n   -   -   smtpd 
-o content_filter=
-o message_size_limit=2048

When I now connect to the server it correctly notifies me about the 
maximum message size.

vs100:/home/simon # telnet 192.168.xxx.xxx 25
Trying 192.168.xxx.xxx...
Connected to 192.168.xxx.xxx.
Escape character is '^]'.
220 mail2.example.com ESMTP Postfix
EHLO mail1.example.com
250-mail2.example.com
250-PIPELINING
250-SIZE 2048
250-VRFY
250-ETRN
250 8BITMIME
quit
221 Bye
Connection closed by foreign host.

Sending a message larger than the default size of 10MB still results 
in an error message.

552 Error: message too large

The message size after BASE64 encoding was approx. 14MB.

Can anyone point me into the right direction, what I'm doing wrong?

BR,
Simon

i agree. But now i have to do it with  postsuper -d QUEUE_ID

in this situation how can i notify the user? i believe there will be somehow  a 
way to inform the user!!!



  

Re: message_size_limit

[Truth Seeker]

i feel like you have to add the following in main.cf (not in master.cf)

message_size_limit = 2048

for me this is working fine... and have the same size limit

You can't change the size limit for the SMTP server alone.
It must be a main.cf setting.

Let the system work for you. Let Postfix remove the
mail when it expires, and let Postfix notify the sender.

There is no automatic notification for postsuper -d. If you want to notify
users that you deleted their mail, you'll need to do it yourself.

However if all you want to do is bounce undeliverable messages, you don't need
to do anything. Just configure whatever maximal_queue_lifetime you find
reasonable and leave postfix alone. When the message expires postfix will
notify the sender.

This is a FAQ. You have a content filter and must disable the address
rewriting either before or after the filter. This is described in
FILTER_README, keyword receive_override_options.

Specifically, message_size_limit is enforced by cleanup(8). Adding
another cleanup(8) service with a different message_size_limit and
choosing it for this particular smtpd(8) with cleanup_service_name
should work.

You sender-based routing in Postfix, does NOT override the recipient
transport, that would be wrong. Instead, for remote delivery, sender-based
routing overrides the nexthop destination. See the link Ralf provided.

But wait, there is more...

The queue manager and the delivery agents can be affected, too.
Depending on how mail gets into Postfix, recipient records may be
sitting at the end of a queue file, and when a delivery agent (or
queue manager) tries to mark a recipient as "done" they get into
trouble when their "message size limit" setting is too small.

That was one of the bugs that was introduced by the VDA patch,

This will prevent forgery of "owned" addresses, but will not restrict
senders from choosing an "unowned" address. For that, one also needs an
access table, that limits senders to use one of the owned addresses.

ldap and transports file

[Kevin Sartorelli]

Hi,
I have Postfix 2.5.6 on a server and having a problem with using an LDAP lookup 
as a transport map.   In my main.cf file I have:
 transport_maps = ldap:/etc/postfix/ldap-groupwise1.conf
My ldap-groupwise1.conf file looks like:
 version = 3
 domain = irdtest.govt.nz
 query_filter = (mail=%s)
 scope = sub
 timeout = 5
 search_base = o=IRDtest
 server_host = 10.40.40.60
 server_port = 389
 result_attribute = mail
 size_limit = 1
 result_format = relay:10.40.40.61
This works great if an email address exists for only one user in the LDAP 
directory:
 postmap -q kevin.sartore...@ird.govt.nz 
ldap:/etc/postfix/ldap-groupwise1.conf
 relay:10.40.40.61
However, when there is more than one account with the same email address I get:
 postmap -q kevin.sartore...@ird.govt.nz 
ldap:/etc/postfix/ldap-groupwise1.conf
 postmap: warning: dict_ldap_lookup: Search error 4: Size limit exceeded
Leaving out the 'size_limit' parameter from the file gives me:
 postmap -q kevin.sartore...@ird.govt.nz 
ldap:/etc/postfix/ldap-groupwise1.conf
 relay:10.40.40.61,relay:10.40.40.61
Which doesn't work too well ;-(
My reading of the ldap_table man page indicates that this will happen for the 
'expansion_limit' parameter, but not the 'size_limit' parameter.

Anyone have an idea how I can get my LDAP lookup to return only one record 
regardless of the number of accounts with the same email address?

Cheers
Kevin

Need to create a mail dead-end or "super" catch-all

[Michael Glenney]

I have a request from one of our developers and I want to see if I can
fulfill it with Postfix.

We have a services platform that has the ability to send out mail to
users.  We have a QA version of that platform that has an old copy of
user data for testing.  For now the SMTP relay option of the QA server
is set to a non-existent host so that mail will not get sent to users.
They would like the ability to test the mail without worrying that a
mail will get sent to one of the users.

I would like to setup a IMAP/SMTP server on the local host and enable
the application to send to it.  I need all mail, no matter who it is
addressed to, to be delivered to one account on the server that will be
accessed via IMAP.  The server can never relay out.  Any message that
comes in on port 25 gets put in this mailbox.

Is this something that can be done with Postfix?  I don't need any hand
holding but a punt in the right direction would certainly be helpful.

Thanks,

Mike G.

Virtual Mailbox Domain

[Mayuresh Kasture]

Hello All,

For some reason, I want to set two mail servers on one machine. One of them
is Postfix. The setup is such that Postfix should receive mails at port 4567
and should send mails corresponding to domain "kmail4u.com" to port 25 of
the same machine where other mail server(coded by me) is waiting for
incoming mails.

I have installed and configured bind9 which properly associates domain
kmail4u.com with the IP address of the machine. And postfix listens to port
4567.

But, when I send a mail to port 4567 addressed to x...@kmail4u.com, I get a
delivery failure with message "mail for kmail4u.com loops back to myself"

This is a part of main.cf file which tries to set this domain as virtual
mailbox domain.

relay_domains = $mydomain gmail.com yahoo.co.in
virtual_transport = smtp:kmail4u.com:25
virtual_mailbox_domains = kmail4u.com
virtual_mailbox_maps = hash:/etc/postfix/vmailbox

And /etc/postfix/vmailbox contains,

@kmail4u.com

Can anybody suggest how I can achieve this set up?

Thanks,
Mayuresh

While my avoid transport(5) lookups over LDAP, so far so good, "proxy:"

This limits the lookup keys to just u...@domain forms in the specified
domain, are you sure that's what you want???

Why would a user's email address ("mail" result attribute) be a useful
transport(5) table result?

You are missing "[", "]" around the literal IP address.

The result format is independent of the lookup key, what is the point
of this?

Yes, but it should be:

relay:[10.40.40.61]

and really should come from the directory. Why not route the whole domain
this really via a simple indexed file transport table?

ird.govt.nz relay:[10.40.40.61]

LDAP does not add any value here, unless users not in the directory have
a different route...

Or is the "mail" attribute of the user in question multi-valued? (Also
not a good idea).

Naturally.

A limit is a limit.

If you want a single result, use a query that always returns exactly
one value, meaning, exactly one matching "entry" with a *single-valued*
result attribute.

Maybe I don't need this at all then.  BUT if I don't have something here then I

Ah, yes - fixed.

I want any user who is in the LDAP directory to be relayed to another machine.  
Any user not in the LDAP gets handled locally.

Correct.  If they are in the LDAP directory then the mail should be directed to 
one point, otherwise it is handled locally.

>> However, when there is more than one account with the same email address

Simple answer - user error.  There shouldn't be but I have no control over what 
goes into the LDAP directory.  While there shouldn't be any duplicate email 
addresses there are and I tripped over one in testing.   Guess I want to handle 
this case in a graceful manner rather than deferring until it is noticed or 
times out.

I was hoping it would only return 1 entry rather than error if there was more 
than one.

OK, thanks.  Wish I had more control over the contents of the LDAP I have to 
look in.

Don't do that.

The "loops back to myself" message is caused when postfix is 
greeted with its own hostname.  One instance needs a different 
hostname.


I fear the gun is pointing at your foot... Before pulling the

Re: Virtual Mailbox Domain

[Mayuresh Kasture]

Thanks a lot Noel for your reply.

I added gmail and yahoo as relay domains when I was playing around
with Postfix. I am new to postfix and am trying to understand it. So,
point is, I can live without gmail and yahoo being listed as relay
domains.

And about my project. It is an academic project. I want to use Postfix
as a relay server. I have implemented my own mail sender and receiver.
Sender sends mails to postfix and postfix relays them to receiver.
But, as of now, I don't want any network delays to be introduced.
Hence, I want all the three processes to be on the same machine.
Postfix listens on port 4567 and my mail receiver listens on port 25.
And kmail4u.com is just a random domain that I picked up(which
according to my knowledge was not in use by anybody at that time) and
made it point to the machine on which all three processes are present,
using bind9. I hope that explains you the project.

Is there any way I can achieve this?

Not necessary or desirable when virtual_alias_domains is used. The user
in question needs to be listed in virtual_alias_maps, and resolve to an
address that is NOT in a virtual alias domain.

Sorry, there is no support in the Postfix LDAP driver for ignoring spurious
additional results.

No, that would lead to unpredictable behaviour because the result order
is not specified. I know that in your case the result is independent of
returned value, but this special case is not specifically singled-out.

LDAP server schemas in some cases have the ability to specify that certain
attributes must be unique across all entries. Administrator error can
be prevented if you make use of any support for such constraints.

We use LDAP, and don't have collisions of primary or secondary addresses
across users.

A loop is detected via any of these three mechanisms:

- Own hostname appears in the peer's "220 hostname ..." banner
- Own hostname appears in the peer's "250-hostname..." EHLO response
- The destination IP address is listed in $inet_interfaces or $proxy_addresses

Thanks Victor. That is the information I required. Now, I am able to
setup mail servers the way I want. Thanks a lot for your help.

conversation with gmail-smtp-in.l.google.com timed out while sending end of data

[June Qiu]

I can send short emails (1KB) from my mailserver (abc.domain.com) to gmail 
account (t...@gmail.com), but for larger emails (7KB), it fails. It gets 
deferred on the mail queue forever. But this same mail can be sent to yahoo.

Am I missing something?
