On my mailserver (bezitopo.org), I use greylisting combined with IP address 
blacklists. Very little spam gets in. A few times a year I get several spams a 
day, because a spammer has bought a new netblock, but even when that happens, 
much of the spam is blocked because, between the first try from an IP address 
(which is blocked by greylisting) and the second, the IP address landed in a 
blacklist.

Most of the spam I get comes through leaf. I can't block it, because my mail 
server sees leaf's IP address, not the spammer's. I filter some of it to a 
spam folder, but that's not as effective as blocking IP addresses.

Moving to a web forum is not going to make spam go away. They get spam too.
