Argh. I hate spam.
I run a few mailing lists on my system, mostly for college alumni and such, and I’m tired of having to deal with moderation requests to grow various parts of my anatomy.
I stumbled across [this site](http://www.jamesh.id.au/articles/mailman-spamassassin/) which talks about how to integrate mailman and spamassassin. Good stuff. Now I just have to see if it works over the next few days.
