Mind you, if your queue size has just shot to 1000 and is growing
without bound because mail is not being delivered, how long will it
take that email to get through the same server?
A: After you have independently discovered or been notified of it and
resolved the problem in some other way, and the queue has finished
draining.
It can be useful to think out some alternate notification methods for
severe mail delivery problems:
send an SMTP trap to a monitor that can page you;
send mail via "netcat" or a tiny SMTP client that delivers directly to an
alternate machine;
etc.
