mail server setup

I've got my crm set up via my personal ~/.procmailrc . It can also be
setup system wide, however I haven't needed that recently.
The crm home page does discuss site wide deployment:
I note one can even use it with Spamassassin. I didn't go that way. I
dropped Spamassassin because it was spawning far too many processes that
were absorbing far too much of my available system resources, so that
other tasks on my server were suffering.
Am I completely happy with the results? No. I still get too many false
positives and consequently still need to look at my spam folder from
time to time. I've white-listed many more email sources than I would
However, I see no more than a dozen or so emails in my inbox daily, and
that's a big improvement over what I was getting from Spamassassin.
