jwz is of course 100% right when enumerating all the ways in which GNU Mailman sucks. He swears by SmartList, a companion to Procmail, but I'm glad I didn't have time to install it before discovering Vladimir Litovka's excellent Minimalist yesterday. Its simplicity and sheer quality is so amazing that I felt compelled to advertise it here right away.

I guess I'm not the only person for whom the task of setting up proper mailing lists has been so frightening that every list with less than dozens of members gets built as a sendmail alias instead. Minimalist is so unbelievably simple that it's real competition are these alias lists, not behemoths like Majordomo or Mailman. And that is saying something. So go get it.
