I am interested in implementing a new feature in Mailman and am in need of a bit of direction. The feature I'm considering would match the subject of an inbound message against one or more regexes and upon finding a match would redirect the message to a different, pre-defined, list. The web interface would have a text box accepting a regex and a drop-down list of mailing lists to redirect the message to. The original sender would get an auto-response saying something like "Based on the content of your subject line, we have redirected your message to this list ..." etc.

I've been picking through the code (very nice and well-documented) and have not been able to find the right spot to insert a bit of code to do what I want. Would anyone be able to point me to the right handler class to modify? Maybe I need a new handler that gets called as a sort of filter? I'm not exactly sure yet and I don't see anything that seems to have that kind of interface.

It would probably be best to add a new Handlers/ module to actually test the subject and requeue the post for another list, but that's the easiest part.

You also need a new Gui/ module and class to implement the web interface to maintain the list attribute that will be used for this. Take a look at header_filter_rules (in Gui/Privacy.py and handlers/SpamDetect.py) for an example.

Finally, you need to modify InitVars() in MailList.py to initialize the list attribute for new lists and you have to increment DATA_FILE_VERSION in Version.py so that MailList will update old lists and add code to NewVars() in versions.py to add the list attribute for old lists upon upgrade.

Of course, any code I write (and which you find useful) will go right back upstream!

Thank you. However, it won't go in 2.1.x, because that's bug fix only and it probably won't be applicable, at least directly, to MM 3.
