Mutt is connected to a Gmail address via IMAP.
When a new message arrives, quite rightly it is marked with 'N' within the index.
Reading the email, this flag is removed ... however any other clients / gmail.com still displays the email as being unread.
I have gone through the Mutt doc but cannot find anything about updating the unseen flag on the server.
Is there something I'm missing or is this a limitation to Mutt?
