While I could offer you sample configs from my Cygwin installation, I've
found out the hard way (this time on FreeBSD) that Exim4 has a very
awkward lock-destination-sites behaviour that requires major manual
interventions to purge the retry/site database to get mails unstuck,
thus I decided I'm not going to install any more of that.

While Postfix is a bit more of an effort to configure (enable
sender-based authentication, enable sender-based relay, enable smtp (not
smtpd)-side tls, enable smtp-side sasl, permit plaintext authentication
on secure tls channels, set up all the maps, I find it's more
transparent and has less magic special casing underneath that confuses
the heck out of myself.
