I use exim's appendfile transport, procmail and a local mutt on my system, they all (to my knowledge) use lockfiles when working with mboxes.

However,
doveconf | grep locksaysdotlock_use_excl = yes lock_method = fcntl mail_max_lock_timeout = 0 mbox_dotlock_change_timeout = 2 mins mbox_lock_timeout = 5 mins mbox_read_locks = fcntl mbox_write_locks = dotlock fcntl pop3_lock_session = no
Do I need to change anything in dovecot's default locking setup? Does it still use lockfiles on mboxes or not? There are some contradictory parameters IMHO.
