To enable Spamassassin on your server, you need to first need to install it. Once installed a few minor changes are needed in your /etc/exim.conf file.
1) Install spamd and spamc:
cd /usr/local/directadmin/scripts ./spam.sh
2) Start the spamd:
/usr/bin/spamd -d -c -m 15
3) In order to get exim to use the spamd program, you'll need to make some changes in your /etc/exim.conf. Change:
# Spam Assassin
#spamcheck_director:
# driver = accept
# condition = "${if and { \
# {!def:h_X-Spam-Flag:} \
# {!eq {$received_protocol}{spam-scanned}} \
# {!eq {$received_protocol}{local}} \
# {exists{/home/${lookup{$domain}lsearch{/etc/virtual/domainowners}{$value}}/.spamassassin/user_prefs}} \
# {<{$message_size}{100k}} \
# } {1}{0}}"
# retry_use_local_part
# transport = spamcheck
# no_verify
to
# Spam Assassin
spamcheck_director:
driver = accept
condition = "${if and { \
{!def:h_X-Spam-Flag:} \
{!eq {$received_protocol}{spam-scanned}} \
{!eq {$received_protocol}{local}} \
{exists{/home/${lookup{$domain}lsearch{/etc/virtual/domainowners}{$value}}/.spamassassin/user_prefs}} \
{<{$message_size}{100k}} \
} {1}{0}}"
retry_use_local_part
transport = spamcheck
no_verify
4) Restart exim: Redhat:
/sbin/service exim restart
FreeBSD:
/usr/local/etc/rc.d/exim restart
The global spamassassin config file is in /etc/mail/spamassassin/local.cf
