An Anti-Spam gateway #11: amavisd-new and Postfix

(NOTE: this is part of the “An Anti-Spam gateway” series)

Not much longer, now…

Add the following line to /etc/postfix/main.cf:

content_filter=smtp-amavis:[127.0.0.1]:10024

and the following lines to /etc/postfix/master.cf:

# amavisd-new
smtp-amavis unix - - n - 2 smtp
-o smtp_data_done_timeout=1200
-o smtp_send_xforward_command=yes
-o disable_dns_lookups=yes

127.0.0.1:10025 inet n - 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 smtpd_error_sleep_time=0
-o smtpd_soft_error_limit=1001
-o smtpd_hard_error_limit=1000
-o receive_override_options=no_header_body_checks

(re)Start postfix. It should be listening on two ports now: 25 and 10025.
