You really don't have a clue on how an SMTP server works, do you? If delivery
fails, it backs up and tries again *later* ... if there is a high volume of
email going through said server, *later* could very well be 1 hour ... and, in
fact, its an incremental backup, so it actually works out to be something like:

Try now, fail, try in 5 minutes, fail, try in 10 minutes, fail, try in 20
minutes, fail, etc ... I'm not sure if its a simple '2x' algorithm, but the
delay between attempts does get progressively greater, so if it fails after
trying at '40 minutes', then it will be another hour and a half after *that*
beofre it will try again, etc ...

Well, when you see a couple of hours delay, then do something *useful* and let
me know ... the only *useful* reports I've had in the past 24 hours dealt with
a problem that Tom reported yesterday and that I fixed within minutes of him
reporting ... the headers that you and Bruce sent me were *from that problem*
...
