What's to hunt?

http://tools.ietf.org/html/rfc2087#section-4.3

RFC 2087 is the IMAP4 QUOTA extension. Section 4.3 has a pretty clear 
example of a GETQUOTAROOT command and its response. Dovecot's response is 
nearly verbatim.

As Rich mentioned, it appears to be a Mail.app issue with the empty-string 
QUOTAROOT name.

There's a FIXME in the dovecot source regarding this:

root = quota_root_init(setups[0], ""); /* FIXME: name? */

See attached patch (against 1.0.3, but from hg.dovecot.org, seems to still 
be valid) for a workaround. It causes dovecot to use a default QUOTAROOT 
name of "DEFAULT". [ I left the /*FIXME*/, since I'm not Timo. :-) ]

Best,
Ben
