 ## Mailbox handling optimizations

 # file. This allows optimizing Dovecot's behavior to do less disk writes at
 # the cost of more disk reads.

 # When IDLE command is running, mailbox is checked once in a while to see if
 # there are any new mails or other changes. This setting defines the minimum
 # time to wait between those checks. Dovecot can also use dnotify, inotify and
 # kqueue to find out immediately when changes occur.
 #mailbox_idle_check_interval = 30 secs
 
 # Save mails with CR+LF instead of plain LF. This makes sending those mails
 # take less CPU, especially with sendfile() syscall with Linux and FreeBSD.
 # But it also creates a bit more disk I/O which may just make it slower.
 # Also note that if other software reads the mboxes/maildirs, they may handle
