Where would I look for documentation for this Yahoo IMAP server requirement, or
how else have you found out what was needed? Is this "1" really a constant?
Technically, it seems to be RFC-2971 and if the Zimbra server side, or Yahoo's
deployment, actually requires this, it is a RFC-2971 violation, see the "MUST
NOT" clauses in section 3 of said RFC.

Does it work to send . ID NIL?
I should rather not like to send random data there unless needed, and GUID
raises some suspicions...

Thank you & best regards
