Mail is delivered very slowly. Qmail queue contains a lot of messages that are stuck:

messages in queue: 14

Queued messages are not delivered unless Qmail is restarted.


/var/qmail/queue/lock/trigger file is missing.


  1. Create /var/qmail/queue/lock/trigger file:

    # cd /var/qmail/queue/lock/
    # mkfifo trigger
    # chmod 622 trigger
    # chown qmails:qmail trigger
  2. Restart Qmail:

    # service qmail restart
