I would definately give the edge to Postfix then.

I use sendmail everywhere myself, but for my main servers I have to roll
my own RPMs anyway to get additional things turned on (also I use the
same source RPM on Linux, Tru64, and Solaris).  Having sendmail removed
wouldn't bother me.

The biggest question is still the upgrade issue; if sendmail is removed
from Core, what will happen on upgrades?  Users will be left with the
old version of sendmail running.

What would be "nice" would be a hack in anaconda to check for a default
config sendmail install (i.e. nothing has been changed since install)
and replace it with the new default MTA (postfix or exim).  If anything
has changed, just leave it alone.  There currently isn't really a way to
handle changing the default provider of a service from one package to

I don't speak for anybody but myself - that's enough trouble.
