dovecot - Jan 2010 - MUA notifications on new mail in a new folder?

If deliver gets run with a non-root userid like this:
< | deliver -m path/to/NEWmaildir >, I wonder, is a connected IMAP MUA
automatically notified, that the new message has arrived in the new folder?
As I see from some experiments with Thunderbird, it has no problems with 
immediate notifications of new mail in previously existing folders, however, it 
has problems with the case of new folder.

-m gets a mailbox name parameter, not a directory path.

Correct. But this is more of a client and/or IMAP protocol problem. Nothing
Dovecot can do about it.
