Do the rebuild.

IMAP requires a unique, stable identifier for every message. Depending 
on how you copied the server-side messages over, that could indeed have 
changed with a new server. Rebuilding takes a while, but all it's really 
doing is getting each message anew, with its new identifier.

Now: whether or not that's really the problem does, as I said, depend on 
how you copied the messages. If it was done by some sort of file 
transfer, server to server, it's quite likely. If, on the other hand, 
you used a mail client to copy things, you should be ok.  *However* -- 
if you copied stuff manually that way, but then changed the MailMate 
settings to point to the new server, the message you saw is almost 
certainly correct. In fact, MailMate warns you about that, as I recall 
from when I did something similar a few months ago.

There's no one rule. What you were told is 100% plausible.
