Exim alas does not fall in that camp, and I need to use Exim as versus Postfix due to the fine grained control it offers over executing UID/GID for filters. Sendmail and QMail are not a reasonable consideration for this case.

Out of curiosity could you elaborate on UID/GID constraints which prevent you from using a postfix/mailman combination?

While things have moved on slightly, the details are still pretty similar to the details I posted to the User FAQ a few years back (see the stuff about TMDA etc). Essentially I run a moderately complex filter system in front of Mailman and various other accounts which requires explicitly defining and controlling the UID and GID as well as the assumed environment (${HOME}, shell context etc) that procmail and other scripts are executed under. Commonly that UID/GID is not an obvious function of the LHS of the address, but rather an arbitrary special case mapping. I can reach the same end under Postfix as of last I checked via vhosts and maps, but that would require also changing my MX and address architecture which I'm not prepared to do.
