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?
