Thank you for this.  I know that I can control the success of the
authentication by modifying the data in the LDAP directory.  However, this
will be a big job to do properly.  I was looking for an IMP solution.

At the moment IMP shows an empty mailbox with the text "There are no
messages in this mailbox." even though the mailbox does not exist and the
response to the "SELECT INBOX" command was "NO Mailbox does not exist".
I would suggest that IMP should distinguish between the two distinct cases
of (a) an inbox which exists but is empty and (b) an inbox which does not
exist at all.
