In Mailman's case, an argument can be made that it and its MTA are working in tandem to perform a function. They know a lot about each other, communicate over a semi-private channel (i.e. localhost:25) are controlled and configured by the same entities, etc.
So again, I have no problem with Qmail rejecting messages from the big bad world that are ill-formed, but it could be more cooperative with Mailman. I guess Qmail rejects ill-formed messages posted from local MUAs too.
OTOH, I can't and won't really argue this point much, because I also feel that Mailman should comply with the appropriate standards, so adding the Date: header for internally generated messages is really the right thing to do anyway.
