Dave - I'm not an expert, but plenty of people (the majority, I would
guess) run amavisd with postfix. Plus the amavisd mailing list is
also very helpful.
What do you mean it was more luck that it worked? In my main.cf, I have defined
content_filter = smtp-amavis:[127.0.0.1]:10024
And in master.cf, I have
#The amavis reciever
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_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o mynetworks=127.0.0.0/8
-o strict_rfc821_envelopes=yes
-o
receive_override_options=no_unknown_recipient_checks,no_header_body_checks
-o smtpd_bind_address=127.0.0.1
#the amavis connector, to send to amavis
smtp-amavis unix - - - - 2 smtp
-o smtp_data_done_timeout=1200
-o disable_dns_lookups=yes
#Stop Postfix from cleaning emails before sending to amavis
pre-cleanup unix n - n - 0 cleanup
-o virtual_alias_maps=
-o canonical_maps=
-o sender_canonical_maps=
-o recipient_canonical_maps=
-o masquerade_domains=
My set up is quite old, so some of these may not be best practice any more.
