after years when everything worked without a hitch, mutt started to say "connection timed out" every ten minutes or so when connected to my remote dovecot imap server. I would need help to figure out where the problem is, on the client or server side, and then how to fix it. Details already are in the dovecot mailing list here https://dovecot.org/pipermail/dovecot/2021-April/121897.html
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.
