Oh.  In that case, what you want are UIDs.

Actually, it would be if the mh code could implement UIDs correctly.  The
problem is that the the mh code uses the filename numbers as the UID; but
then has to account for the mh compact command, which renumbers all the
files.

If you never use the compact command, then IMAP UIDs would be just what
you need.  Otherwise, you need to have some other means to tie a permanent
UID to a particular message, while preserving the IMAP requirement of
being strictly ascending in the mailbox.
