(a) would be my preference.  An alert wouldn't even need to be sent --
when mail stops it will be noticed rather quickly.  And as someone else
pointed out, an email alert may not make it anyway (it probably gets
routed through MailScanner).

There's also the question of whether mail should stop if ANY of the virus
scanners are unavailable or only if ALL scanners are unavailable.  I
don't have a suggestion for that.  If you have only 1 virus scanner
than both conditions are met so it's obvious what to do there.
