This is how I would enable spamassassin, along with amavis and clamav. Unlike the amavis configuration with maia or the one that partially comes with ispcp, this method uses amavis as pre-queue filter. That makes it possible to reject spam mails instead of only tagging them...
Code:
apt-get install amavisd-new clamav spamassassin clamav-daemon lzop rpm pax unrar zoo arj p7zip-full lha arc cabextract ripole
add the following lines to /etc/postfix/master.cf after:
Code:
smtp inet n - - - - smtpd
Code:
-o smtpd_proxy_filter=localhost:10024
-o content_filter=
localhost:10025 inet n - n - - smtpd
-o content_filter=
-o smtpd_proxy_filter=
-o smtpd_authorized_xforward_hosts=127.0.0.0/8
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,reject
-o smtpd_data_restrictions=
-o mynetworks=127.0.0.0/8
-o reveive_override_options=no_unknown_recipient_checks
remove the following from /etc/postfix/master.cf:
Code:
amavis unix - - n - 2 smtp
-o smtp_data_done_timeout=1200
-o smtp_send_xforward_command=yes
-o disable_dns_lookups=yes
localhost: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 smtpd_override_options=no_address_mappings
-o mynetworks=127.0.0.0/8
-o strict_rfc821_envelopes=yes
/etc/master.cf will look like:
Code:

EDIT: Consider using a ramdisk for the amavis temporary directory... this will boost performance... and let you use a higher $max_servers count...
