I'm working on the new mailing list system for perl.org. Want to test? Email email@example.com to subscribe to the test list, firstname.lastname@example.org to subscribe to the digest version. Email email@example.com for more commands.
If you subscribe, prepare to get a bunch of test mails, of course. :-) Also, if you subscribe, feel free to send test mails to the list.
Sverything should be working like a regular ezmlm list. The initial version (where it is at now) is just a system for managing the list configuration in database and for replacing all the .qmail-* files with one(!) .qmail-default file calling one program. It's also written so we can make qmail (or another mailer) just write to a Maildir and have Ballistic pick up the mails from there (it emulates qmail-local / qmail-command). It's great.
(if you are curious, then the code is in Subversion, use guest/guest for the login. No documentation yet and I wholeheartedly will not recommend that you try using it just yet).
