This was actually technically impossible until RFC 5530 defined an  
OVERQUOTA response code.  I've just added code to IMP 5.1 that will  
workaround this issue by permanently deleting the messages instead of  
moving to Trash.  However, this is entirely dependent on the IMAP  
server (I think Dovecot supports it).

Alternatively, use a IMAP server that supports "soft" quotas.
