SpamAssassin and Amavisd: Go Ninja On Your UBE Woes - page 3
Building a Better Gateway
Now it's time to set up Postfix to use Amavisd-new. This is a fairly generic configuration, ace Postfix admins may futz and tweak to suit themselves. If you're not real experienced with this part of Postfix, the book "Postfix," by Richard Blum, is a first-rate reference.
Add this to the end of
smtp-amavis unix - - n - 2 smtp -o smtp_data_done_timeout=1200 -o disable_dns_lookups=yes 127.0.0.1:10025 inet n - n - - smtpd -o content_filter= -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks -o local_recipient_maps= -o relay_recipient_maps= -o smtpd_restriction_classes= -o smtpd_client_restrictions= -o smtpd_helo_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,reject -o mynetworks=127.0.0.0/8 -o smtpd_authorized_xforward_hosts=127.0.0.0/8 -o strict_rfc821_envelopes=yes
Then add this line to
content_filter = smtp-amavis:[127.0.0.1]:10024
Then do a complete stop-start cycle for Postfix:
# /etc/init.d/postfix stop # /etc/init.d/postfix start
And you now have a nice spam filter on your mail server. Start sending yourself the saved spams for testing.
You can run SpamAssassin on Postfix without using Amavisd-new. See the SpamAssassin Wiki for howtos on different ways of installing and using SpamAssassin. ClamAV needs Amavisd-new, so it's easy to let it manage SpamAssassin as well.
Come back next week for the exciting installment on installing and using Clam Anti-Virus.
