Something seems badly broken on your IMAP server.

IMP correctly asks for the list of messages in the mailbox:

(1307732082,2502) C: 4 UID SEARCH RETURN (ALL COUNT) ALL

However, the IMAP server reports that ALL UIDs between 316 and 615 exist:

(1307732082,2506) S: * ESEARCH (TAG "4") UID ALL 316:615 COUNT 131

However, that can't be right since it also reports that there are only  
131 messages in the mailbox, but the UID response indicates that there  
is 300 messages.  So the ESEARCH response is broken.

You wouldn't see this on other IMAP clients (e.g. IMP 4) because many  
of them don't support the new ESEARCH return.  You could work around  
this by disabling the ESEARCH extension in imp's backends.php file, at  
the expense of less efficient SEARCH queries (assuming that regular  
SEARCH queries are not broken).
