Scott,
The Imail server normally processes around 175,000 messages/day, so
it just started overnight. There hasn't been a real increase in the traffic
to it, to have caused this problem. As for the errors, I was getting a lot
of 10054 errors in the SMTP log, but those have ceased tremendously, to
where there are still a few. I have check the harddisk on the machine for
problems and found none and have also defragged the drive. I just tried to
send a test email from an account on the Imail server, to another account on
the Imail server that forwards the message to the Exchange server and that
went through just fine, delivering in less than a minute. I also just tried
sending a message from Hotmail to an account on the Imail server that
forwards the message to the Exchange server and that went through just fine
also. I traced them through the Imail SMTP log and didn't see any errors or
anything with them. Any other advice?

The first questions are how much E-mail do you normally process, and how
long did it take the spool to get to that size? For example, if you
normally process 1,000 E-mails/day, that's 78 days worth of E-mail, which
would indicate that there is a much larger than normal volume of E-mail (a
spammer, virus, or mail loop would be the first suspects). If you normally
process 200,000 E-mails/day, and the 78,000 files accumulated overnight, it
could be a normal volume of E-mail that isn't being processed as normal.

That's encouraging -- the E-mail is being processed, albeit slowly.

The first thing to do is identify whether your load recently increased
significantly or not. If so, you need to identify the source of the
increased load, and get rid of it (if appropriate).
The next step is to check the log files to see what is happening. Are
there lots of warnings/errors? If you track an E-mail through the IMail
and Declude log files, can you see if there is a long delay in delivering
E-mail (for example, if your primary DNS server stops working, there may be
long delays waiting for timeouts, which would slow down mail delivery)?
