Also one good rule of thumb is to have it ignore emails that are too
large for it. If a huge email gets in there and spamd it will bring your
mail server to its knees. And its not a bad idea to drop privileges for
security reasons. (especially if you run it as root)
Here is how i'd do a /etc/procmailrc
DROPPRIVS=yes
:0fw: spamassassin.lock
* < 256000
| /usr/local/bin/spamc
One of the big reasons for spamd/spamc is that this configuration works
better in system/network wide configurations of spamassassin. If your
just sitting there on your desktop running spamassassin you probably
just want to run 'spamassassin' so your not wasting resources the
majority of the time your not running mail through it. spamd/spamc also
allows you to network between the c client and the daemon. So if your a
huge installation you can setup spamd on a system just for that and
spamc on each of the MTA or relays as not to compromise the performance
of your mail systems themselves.
Atleast, this is my understanding of it. Correct me if I'm wrong.
