connection to dovecot times out about every ten minutes

[Marco Fioretti]

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?

Thanks,
Marco
