I am trying to "collect" methods to setup postfix in an HA
configuration, for "outbound" relay (no MUA involved). a use case is
using multiple postfix boxes to relay mail out for one or more exchange
servers. there are many possibilities. which one is
"good/recommended/easy/blahblah"? This is somewhat off topic since the
problem is mostly on the client (exchange or other) side rather than
postfix. but I think this is a real need. and if I get enough infos, I
can aggregate them and submit that as a howto/readme.
