I have similar reservation on Dan Bernstein.  While I've been
impressed with the thru-puts that QMail can accomplish (CP here uses 
a QMail derivative), due to Dan's behaviour it is not one I freely

The behaviour of a single admin hardly reflect on the MTA entire.  I
like Exim.  Phillip Hazel (the author) is responsive and active on
the mailing list that supports it.  The config files are human
readable and easy to understand.  The admin controls and logging are
well developed.  Performance is good and often similar to QMail and
Postfix.  And best of all: I don't need a Bat Book.

Postfix is impressive.  I've been archiving the Postfix lists at
Kanga.Nu for a while now, but don't run the MTA myself yet (happy
with Exim and more more important fish to fry than an MTA change).
I have a number of friends, some running large sites and large mail
loads, that are happily running Postfix.  I'm encouraged by the
traffic I see on the lists and by Vietse's behaviour on the lists
(especially compared to Dan B).
