Read the spec for Mailman 3.0. Looks like it will be pretty good. The feature that I’m interested in, and I’m annoyed I can’t do this with my current version of Mailman, is to be able to put a link to the web archived message in the bottom of the outgoing SMTP message. I.e. so there’s a link back to that message on the web in the message itself. Would be really handy for referencing. At the moment if I want a link I have to go to the web archive for the particular list and find it.
While I was reading the Mailman 3.0 spec I noticed a link to Postfix Virtual Domain Hosting Howto. I think I might have read (at least some of) that before. But… reading that is now definitely on my TODO list.
