I'm going to butt my nose in where it doesn't belong and insert my opinion here. :) Here's the setup we run, and it works incredibly well. Sendmail mail/p5-Mail-SpamAssassin mail/spamass-milter mail/spamass-rules mail/spamass-rules_du_jour sysutils/clamav (built with miltering) Add to your .mc file: INPUT_MAIL_FILTER(`clmilter',`S=local:/var/run/clamav/clmilter.sock, F=, T=S:4m;R:4m') INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass-milter.sock, F=, T=C:15m;S:4m;R:4m;E:10m') crontab nightly /usr/local/bin/rules_du_jour Make sure your ports tree is cron'ed to update regularly, have the freshclam daemon running, and I'd strong suggest subscribing to the RSS feed at http://www.freshports.org/sysutils/clamav Just my 2 cents. ;) On Tue, 17 May 2005, Warren Block wrote: > On Tue, 17 May 2005, Charles Lamb wrote: > >> Would I want to enable milter with clamav? > > Depending on your needs, maybe.
