spamassassin/clamav setup problem

[dipeshmehta]

Hello,

I have setup my ubuntu 8.04 LTS server as guided in "The Perfect Server (by Falko)". I have not installed ISPConfig.

Since, this howto do not include spamassassin and clamav setup, I have setup them, as guided in "Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 LTS)".

I am not using MySQL as well as virtual users, I am using system users, therefore I jumped directly to "9 Install amavisd-new, SpamAssassin, And ClamAV" part of the said howto.

Now, my mails transmitted into internal network, do not get delivered to destinations. If I comment out the added lines in postfix's main.cf and master.cf, it works fine without spamassasin / clamav interaction.

I know, there should be some silly matter which needs to be configured but cannot figure it out myself. Any suggestions welcome.

What's in your mail log?

What's in /etc/postfix/main.cf and /etc/postfix/master.cf?

Hello,

Sorry for re-opening the thread after a long time. Since, the setup is on my production server, I have not been able to run test cases as much.

Please check my postfix config files as under:

==================

I have noticed that while sending mails postfix do not read sender_dependent_relayhost_maps and smtp_generic_maps if amavis-new is there in postfix config files. Mails sent to local users do not deliver at all - and mail que status is "mail transport unavailable". Whereas for mails sent to out of the world, it does not being relayed through my ISP mail server, and therefore almost all recipient server reject it.

At present I have comented out the lines related to amavis, and content filter, and the set up is running very fine.

Please help me out.

Thanks in advance.

Hello Falko,

The Static IP 59.96.84.206 has been provided by my ISP, and following details has been given by him:
IP 59.96.84.206 is part of AS
9829 BSNL-NIB National Internet Backbone
and the Networks 59.96.64.0/18 59.96.80.0/20

Reverse DNS (PTR) exists and claimes to be: static.vadodara.bb.59.96.84.206/24.bsnl.in

Forward DNS for static.vadodara.bb.59.96.84.206/24.bsnl.in is: 59.96.84.206

DNS ist consistent.


Moreover, if the said error occurs it means that my mail has not been relayed and fired directly. Similarly, what about internal emails?

Does 2020503.mx2.banlab.com use valid nameservers in /etc/resolv.conf?

Hello Falko,

Thanks for showing interest to solve my problem.

At this point, I think we are going towards something wrong way. So please let me give a brief idea about my system and environment.

The host banrjt.banlabs.net is my ubuntu server which has been situated at my office. About more than 50 machines running Windows XP / vista are connected to the same. I have been using ubuntu server as mail server for my internal mails.

The domain banlab.com is being hosted at my ISP for webhosting as well as email hosting. We have some 15 different mail ids at banlab.com.

I use getmail (http://www.howtoforge.com/debian_etch_getmail) to fetch mails from ISP POP Mailboxes. (*@banlab.com). The mails are fetched for pop_ispmailid@banlabs.net and there I use .forward for forwarding the mails to associated internal user accounts.

To send mails internal (i.e. user1@banlabs.net to user2@banlabs.net), I do not need to configure anything, it works fine. To send mails to outside world, I use sender_dependant_relay_maps, to relay through ISP mail servers (i.e. smtp.banlab.com). Further I use generic maps (http://www.postfix.org/ADDRESS_REWRITING_README.html#generic) to rewrite from: address for outside world.

All these setup runs without any problem, if I remove
#content_filter = amavis:[127.0.0.1]:10024
#receive_override_options = no_address_mappings
from /etc/postfix/main.cf and
#amavis unix - - - - 2 smtp
-o smtp_data_done_timeout=1200
-o smtp_send_xforward_command=yes

#127.0.0.1:10025 inet n - - - - smtpd
-o content_filter=
-o local_recipient_maps=
-o relay_recipient_maps=
-o smtpd_restriction_classes=
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restictions=
-o smtpd_recipient_restictions=permit_mynetworks,reje ct
-o mynetworks=127.0.0.0/8
-o strict_rfc821_envelopes=yes
-o receive_override_options=no_unknown_recipient_chec ks,no_header_body_checks
-o smtpd_bind_address=127.0.0.1
from /etc/postfix/master.cf

Now coming again to my problem, if I enable above lines in main.cf and master.cf. In the above mentioned log entry 1, you may notice that...
i. The mail is originated by dipeshmehta@banlabs.net (generic map: dipeshmehta@banlabs.net edp@banlab.com)for manishoza@banlabs.net (generic map: manishoza@banlabs.net edp@banlab.com)
ii. The mail is transported as from edp@banlab.com to edp@banlab.com, that means it didn't recognised that the mail is internal, and therefore passed through generic maps.
iii. The mail transported as from edp@banlab.com but didn't relayed through smtp.banlab.com (sender_dependant_relay_maps: dipeshmehta@banlabs.net smtp.banlab.com)
iv. Due to security measures opted by ISP at banlab.com, the mail was rejected.
v. For this mail sender_bcc is not generated, which recipient_bcc is generated.

The similar things happens for log entry 2a & 2b, the mail is transported directly i.e. without relay, and received at yahoo.

Thanks again for sparing your time to diagnose.

I'm afraid I don't know what's wrong with your system.

Thanks Falko for sparing your time to sort out the issues, no matter whether solved or not.

Btw, if you wish, I PM you with access rights to my server, to check the things.
