btw, in case anyone was wondering - both servers came back online
my one that was down should have come back online 15 hours sooner than it did (still, 16 hours downtime isn't that bad) but there was a small typo made last month that caused a small breakdown in communications (the other mail server wasn't being used due to a small typo - so when that server went down i lost inbound email, resulting in them not being able to send me the correct passwords...)
