Spam filters?

[axemanxt40]

Hey guys does anyone know the name of a Spam filter program where you can make your own custom rules, such as one to block emails without subjects?

Mailwasher is one such program.

It's not a spam filter program specifically, but procmail might help. You can write your own filters in thunderbird.
