[MlMt] Mailbox count = Recent doesn't match server's \Recent count

Aside from the fact that the IMAP \Recent flag is not inherently useful, 
the MailMate displayed count does not match what the server says.  All 
my mailboxes show non-zero counts when the counter is set to "Recent," 
but as a test I used telnet to connect to my server and SELECT a mailbox 
that MailMate displays "215" when the counter is set to Recent.  When I 
SELECT that mailbox, the server reports 0 Recent:

* FLAGS (\Deleted \Seen \Recent \Answered \Flagged \Draft $MDNSent)
* OK [PERMANENTFLAGS (\Deleted \Seen \Answered \Flagged \Draft 
$MDNSent)] OK
* 657 EXISTS
* 0 RECENT
* OK [UNSEEN 91] first unseen message
