[H-GEN] Replacement?

Well, I've been thinking about the whole mail server issue (haven't really had
time to look into my sendmail problem, hence no update) and I am thinking that
sendmail might be more than I need anyway.

So I'm going to initiate a religious war by asking what MTAs people use
and why? All responses welcome. I'm running FreeBSD 4.7 as a firewall, mail 
server, DNS (mostly internal at the moment, though accessible from outside)
and of course ADSL gateway.

Minimum requirements:

Masquerade entire domain, including envelope. ALL mail going off that box
or the workstations being the firewall should be masqueraded. Possible
exception is the "From" field if it is set to an entirely different domain (in
case I am subscribed to a mailing list on a different address) but I can live
without that if necessary.

Some form of spam filtering - currently configured to use RBL and bounce
domains that can't resolve. I would also like to be able to bounce mail
that is obviously spam. For example, our bigpond email address is forwarded to
our home mail server. Except for bills, most mail going to that address
is spam. The envelope is addressed to our bigpond account, but the To field is
a non-existant email address on our system. Whenever we see these we know they
are spam. If there's any way to blackhole them that would be wonderful.

Needs to handle aliases and be specified a few domains to relay (duh).
Don't give a damn about the mailbox format, as long as there is an IMAP server 
that can read it. Currently using imap-uw, but can survive if I have to
switch.

Security is a major issue. Setuid binaries - especially sitting on an
open port ala older versions of sendmail - make me uncomfortable.

Performance is not an issue at the moment. There's only two people using
the damn thing, and it's a 1.3 ghz celeron so short of a DOS it should
be able to cope with anything I throw at it. However I would like any
opinions about comparative performance of MTAs.

Thanks all.
