If you enable any kind of personalization, then you'll get individual messages being delivered by Mailman to the MTA.  This includes footers with a user-specific string to tell them what their particular link is to unsubscribe from the list, etc....

You'll have to disable all types of personalization and VERP to get more than one recipient per message being sent to the MTA.  And qmail is not an ideal MTA for maximum performance on a mailing list -- I can run rings around it with postfix.
