I don’t read mail on Windows machines, nor with a broken mail reader. I don’t worry about getting the latest email virus. But when my email address is receiving literally a hundred Windows viruses a day, I get annoyed.
So I’ve installed Clam AntiVirus on Rakim as a Sendmail milter. If you use Rakim for email, you shouldn’t be seeing your inbox full of this crap any more. Yay.
I have SpamAssassin installed too, but I don’t have it set up in a site-wide manner. If you want to use it, edit your dotfiles accordingly.
