(02-22-2009 06:08 AM)rbtux Wrote:  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 smtpd_override_options=no_address_mappings
   -o mynetworks=127.0.0.0/8

/etc/master.cf will look like:
