I really didn't want to rebuild everything as that would take forever.  
I only wanted to rebuild the one mailbox.

I just left MM running while I was doing other things, and when I came 
back several hours later, MM had resynchronized.  I have no idea what 
caused it to realize it needed to do so but am glad it did.

No, they were gone.  I used telnet to connect to the IMAP port on the 
server and confirmed that the mailbox had far fewer messages than it 
should have.  I assume there was a problem with my auto-expunge system, 
but I am mystified as to what happened or how.  I have a virtual mailbox 
with the "Mailboxes" section set to only the "Deleted Messages" and 
"Junk" mailboxes of the account, and a "Conditions" set to "Received 
date" "is not within last" "9 months" and the "Rules" section set to 
"Delete Permanently."  I do not see how it could possibly have affected 
messages that were in the Inbox, since it is set to only include 
deleted/junk messages, and I don't see how it could have deleted 
everything up to a few weeks ago.  I've disabled the rule.
