I've heard numerous people say it and I've read it in several online
articles and they *could* all be lying (you're right, I don't know for
certain) but I'm willing to put a reasonable amount of confidence in
something I've heard many different times from many different people.

Having said that, Postfix was pretty much a drop-in replacement for
smail (in my experience) which is mostly a drop-in replacement for
sendmail so, while I don't know for certain, I'm reasonably confident.

Absolutely.  But in the case that I'm currently concerned with, it is an
entirely new installation.  Therefore it seems worthwhile to explore
options other than sendmail (which is somewhat bloated and has a dubious
history in security) before committing to any particular MTA.

(Anyone with comments/feedback/experiences on other MTAs then please
feel free to email me on or off list as appropriate.)

Christian.
