[MlMt] Duplicated sent messages (in Sent Mail and in filed-in box), Gmail

[Gary Hull]

MailMate is an IMAP client. Gmail uses an undocumented midification of 
IMAP that it calls Gimap. MailMate is not completely compatible with 
Gmail. IMAP services like Runbox and Fastmail are fine. Apple's Mail app 
ran into the same problems with Gmail. Google is not particular eager to 
have people use outside clients, so they are not of much help.

Here are the workarounds:

And I think there may be more tricks subsequent to this writeup: check 
the list archives.

Basically, the simplest approach is to not use Google's labels, which 
are proprietary and non-standard. MailMate is compatible with IMAP tags 
and cagetories. Google's labels present themselves as IMAP mailboxes to 
clients, causing duplication. I think Benny has an approach for people 
who must use the labels (search the archives).
