Can't argue with you here.  They have a dedicated SMTP version but it's
very limited and acts as an open relay, thus can't be used in most
configurations.
The system I'm using this on is loaded lightly enough that Amavis doesn't
cause us any problems.  Even then, Amavis is much less load than running
something like Spamassassin.

This can be worked around.  We have automated scripts for nightly update
and simply do the monthly manually (only takes about 15 minutes or so)
but I can easily imagine that the monthly update could be scripted as
well (although we haven't bothered).

Yes.
