MS Outlooks do put those extra white-spaces in there blatantly..
I think you'll find the world a little easier to deal with if you run
outgoing relay and incoming MX on separate hosts. Your outgoing relays
will then have to deal with Outlook and your incoming MXes will have to
deal with spammers, random probes and other people's outgoing relays. A
nice division of responsibility.
Ten or fifteen years ago some smart admin at EUnet told me it's better
to run one service per host. I didn't understand why then. Now his
advice seems very, very good.
