Postfix or Sendmail for MS & SA?

Hello all,

First of all by asking what's best I know I could be developing a flame
war, although the MS list have been mostly free of those. Let's say it's
not my intention.

Ok now the real question;

As some of you might know I'm an consultant (he sorry, it's a living.)
an large customer of my company asked me to look at possibility of
deploying an anti-spam, and potential anti-virus solution.

Personally I'm a big fan of the mailscanner & spamassassin combination.
In the past I build the sendmail, MS & SA combination for several semi
large companies (1000 users or so). The customer now is in the order of
50.000+ users, current estimate 2 * X FAST intel boxes, due to
geographical redundancy. (3 < X > 8)  (please don't ask the cust's name..).

I could build the sendmail, MS & SA combo again, but I'm looking at
postfix as well. The idea is to deploy mailscanner in front of their
commercial mail platform. The reason to deploy postfix is due to the new
feature in PF 2.0.0, with local_recipient map, which is easy to
integrate with ldap. The data store of the commercial platform.

I'm fully aware sendmail support ldap as well, but not as easy to
implement. And for this setup where the box will only be an "simple"
relay, a bit heavy.

The real questions (didn't i mention that before?):

1) Postfix is "recently" added to the list of supported MTA's, it's not
as long supported as Sendmail. Can somebody provide some educated hints
in regards to stability etc.

2) Recently Wietse Venema (The auther of Postfix) stated that he had
some issues with the way MS operated. I can understand his point of
view, but  nevertheless I like Julians approach. But did somebody ever
encountered (major) issues in this area?


P.S. I didn't look at any of the other MTA's due to my personal lack of
knowledge, I only have a (lot of) experience with Postfix & sendmail.
This basicly ruled out the other MTA's, sorry for those fans.
