No, it cannot, unless you use spamassassin as the LDA, which is
deprecated. Exim can use multiple sequential filters as part of the
LDA (which are all run as the user).

Stop harping on that and respond to my points, if at all. Even
a modular architecture can support filters as part of the LDA;
Postfix does not.

So you suggest .forward files for a machine hosting about 1700
Windows users?

If you object to exim because of its monolithic setuid nature, how
can you possibly advocate procmail?

Sure, it's run as the user. But it's a bloody performance hog. Try
that with 1700 users and about 130 to 200 mails per minute, and
you'll find that it does not work.

If you do SA on a system-wide basis, the auto-whitelisting feature
is a problem, and Bayesian filtering is basically useless.

I did not say so.

Which (sensible) MTA does not do it this way?

I believe I said before that I completely agree. This is not the
issue being discussed.

You are making a fool of yourself.

Did I say that the From address was the only feature to base routing

Also you (and Wietse) are failing to see the value for
store-and-forward relays.

Anyway, this is pointless. You just read my last post on the issue.
