In this case I think I see a problem: if I disable 'newmail_notify',  
but leave 'refresh_time' set to "Every 5 minutes", my client stops  
polling for new mail, in fact I don't see any IMAP connections at all.  
Is it UI-dependant, as in do I have to have Mail window displayed?

Confirmed, unfortunately we're stuck with it for quite some time. I  
wish I was able to switch to Dovecot.
