How can you emulate a mailing list in Django?

I'm on a project which is trying to write what amounts to a Mailing List app in Django, and we're running into a couple of problems/questions.

The code we have so far doesn't set various List headers, and re-sets the To header to be the person we're sending it to, instead of the list address.

Now, we can work our way through all these fiddly little details, but I was wondering if anyone had any code which already did this sort of thing that we could crib from, so that we don't have to go through all the trial-and-error ourselves. Specific sections of RFCs that showed us what we should be sending would also be useful.

Thanks,
Blake.

Solution

RFC 2919 has some info and more references on this.
