We've been using Postfix with MailScanner for well over a year now.
There has never been a problem between the two applications for us. We
process 35k-50k messages per day for ~300 users on an athlon 1.3 GHz
box.

I have a good deal of respect for Wietse Venema's work on Postfix. The
documentation is very very good. For anyone who hasn't, it's worthwhile
to take a look at these docs even if you don't intend to ever use it as
your MTA. I learned a lot about email just from studying this stuff:

http://www.postfix.org/documentation.html

Previous versions had a great diagram that showed how all the pieces of
the system fit together and the various routes a given messages could
take.

Having said that though, Wietse has a reputation for being a bit
grouchy. Julian is a very much more personable guy and much more
approachable. :) I wouldn't even think of asking Wietse to change
something for fear of getting my head bitten off[0]. MailScanner and
this list are great, regardless of what Wietse thinks of them.

[0] disclaimer: I haven't had reason to approach Wietse about anything
either. This is intended with tongue in cheek. I would be intimidated if
I ever had a reason to contact him, nonetheless.
