I think many of us have something similar to this happen at least once. In our case it was a single message that crashed the queue mgr which is likely the cause of the message buildup for you. Searching the log for "error 500", I think, resulted in our finding the offending message. Removing that resolved the problem.

As for email sitting in the spool for two months that would be a big problem for anyone. Imail is currently trying to find an answer for me with regard to T files with matching D files being left in the spool. These are mostly spam but we have found a few valid emails among them.

There's also an issue of smptd32.exe memory "racing" or leaking which seems to be limited to our instance of imail. Strangely this is a brand new server bought with the intention of running 2006. Our memory problems started back in 8.0x though.

Today I was blessed with a mail server on the fritz.  The CPU was pegging at
100%, and I had difficulty doing much of anything.  I've noticed that the
CPU was maxing itself out alot lately, but wasn't figuring out exactly why
(I guess it's times like these when you are forced to figure it out!)
Anyway, I pulled up the Task Manager and saw that there were several
instances of ntvdm.exe, smtp32.exe, etc.  The spool was filling up fast (hit
over 3000 messages rather quickly).  A search through the archives said
something about the "heap" issues and pointed to a potential solution on
Microsoft's website regarding editing the config.nt file.  
 
I stopped all the iMail services, moved the files from the spool folder, and
edited the config.nt file.  After a reboot, everything seems to be working
great - better than ever (knocking on wood).  I moved the files back into
the spool folder and it is processing great.  Perhaps I dodged another
bullet.
 
My question is - it appears that this "magic" fix took care of things - but
why now?  Also, when it started processing messages again, I noticed several
messages (mainly from website forms that were filled out) that were from two
months ago.  I'm a little confused by that (and so are our clients who are
yelling about it).  
 
For what it's worth, we are on a Windows 2000 server with iMail 8.22 and the
latest Declude suite.

Any thoughts?
