The default value of $timeout is 10 minutes.  At that time, Mutt would 
typically sent a STATUS command to check for new mail in your mailboxes.

Starting with version 1.9, Mutt added polling for IDLE, NOOP, and STATUS 
commands to check for a dead connection.  It sends the command and then 
waits $imap_poll_timeout seconds for a response from the server.

You might try increasing $imap_poll_timeout and seeing if that helps.

If not, you could enable debug output, using "-d 2", and see if that 
provides any clues.
