Hi Kevin, imap_poll_layout was not set in my murttrc file.
Setting it to 0, which according to manual should disable it, just made mutt freeze set imap_poll_timeout = 600 made it freeze too, but eventually recovered, and had to reopen the inbox set imap_poll_timeout = 60 makes no difference wrt the original problem, I just see the "Logged out" dovecot messages on the remote server appear every minute. Launching mutt with the -d 2 option did not produce anything visible. Where should debug messages appear, btw? In mutt itself, or in some log file? What could I try next?
