Then reduncy would be important - and mailscanner can easily be
incorporated, various methods, to make sure that IF it should fail, it
wont stop mail, or mail could be scanned by a 2nd server on lesser
hardware while you repair the first, or hold all mail, whatever, no need
to make mail delivery dependant on MS being up?
