If not set, it defaults to 15 seconds.

Setting it to 0 turns off the polling.  So Mutt is sending the 
IDLE/NOOP/STATUS and trying to read the response, without polling the 
connection first.

If Mutt freezes in that case, then the connection to dovecot has died.

Setting it to 600 means Mutt will wait 10 minutes for a response from 
the server before declaring the connection is dead and trying to 
reconnect.  If it then reopened the mailbox, that also means the 
connection to dovecot died.

This flag produces a file ~/.muttdebug0 in your home directory with 
debugging output, including IMAP commands sent and received.

Perhaps you can compare that and the dovecot log, and see if you can 
find out why all the "logged out" messages are appearing.
