Anti-spam filters

[Martin Marques]

I'm moving some mail addresses from one server to another, and I was
thinking about changing my anti-spam system.

Today, I'm still using bogofilter for my personal account, but it would
be nice to have a multi-user anti-spam system which can have per-user DB.

I was thinking about dspam, but I see that there are no rpm, at least in
yum and with some google searching (not to much, maybe I should look a
little more).

Now, what other options do I have?
