Postfix - Amavis-New - Spam Assassin - Razor - ClamAV Gateway Server - Setting up White / Black Lists

Hello,

I have an Email Gateway Server running RedHat 9 with the latest versions of Postfix/amavis/SpamAssassin/ClamAV and Razor installed. All its being used for is to Spam and Virus check static SMTP routes before it reaches its final detination mail server.

It hosts multiple domains going to multiple detination IP addresses.

Basically what i need todo is setup White / Black Lists per domain. So for each domain we host they have there own white and black list. Ive looked everywhere for documents on how to set this up but ive been unlucky. I also need to know how to forward spam for each domain to their own Spam Box.

I know this can be done somehow as i use it in Cpanel.

Could someone please help me out.

Thanks

Dan.

You can set up white/black listing per recipient domain in amavisd.conf. Look at the end of Section V for ENVELOPE SENDER WHITELISTING / BLACKLISTING - PER-RECIPIENT.

Set up entries like this:

$per_recip_blacklist_sender_lookup_tables = {
'.sub1.example.com' => read_hash({},'/var/amavis/sub1-blacklist.txt'),
'.sub2.example.com' => read_hash({},'/var/amavis/sub2-blacklist.txt')
};
$per_recip_whitelist_sender_lookup_tables = {
'.sub1.example.com' => read_hash({},'/var/amavis/sub1-whitelist.txt'),
'.sub2.example.com' => read_hash({},'/var/amavis/sub2-whiltelist.txt')
};

Then create /var/amavis/sub1-blacklist.txt, /var/amavis/sub2-blacklist.txt, etc. These files take one address per line, comments start with #.
For example, in /var/amavis/sub1-blacklist.txt:
spammer@spamcity.com
anotherspammer@timbuk.tu      # this is a comment

To forward spam to each domain's own spam box, look in amavisd.conf Section IV for the spam_quarantine_to directive. Use something like this:

$spam_quarantine_to = new_RE(                             # per-recip multiple quarantines
  [qr'^.*@sub1\.example\.com$'i => 'spam-box@sub1.example.com'],
  [qr'^.*@sub2\.example\.com$'i => 'spam-box@sub2.example.com'],
  [qr/.*/                                => 'all-other-spam@example.com']
);

You may also want to set up the $virus_quarantine_to directive in a similar way.

Adjust paths and filenames to suit, and don't forget to "amavisd reload" after making config changes.
