It was on the list yesterday and Brad's reply is at
http://mail.python.org/pipermail/mailman-users/2005-April/043964.html

Brad's reply is that this is an Exim question and Exim lists, etc are
much more likely to provide a useful response than this list.

In order to prove Brad correct, I'll point out what I (not an Exim guy)
see, but I can't tell you what to do about it because I don't know.

This seems to me to be saying that Exim is trying to pipe the message
(presumably to the mailman wrapper), but it is running as User 0
(root) which is on some Exim configured list (never-users) of users
not allowed to do this.

I don't know what to change either.

Actually, I think the above is right. Mail to the list post address
(rbc at daevid.com) should be piped to the mailman wrapper exactly as
shown in the response. The router = and transport = stuff is an Exim
incantation that tells Exim to do its Mailman magic which results in
the pipe as shown.
