notifyd  is  a  daemon  started  from master(8) that handles notification requests on behalf of lmtpd(8).
       Notifyd accepts the request and performs the notification using the method specified in the request.

       Note that for notifyd to run properly you  must  set  proto=udp  in  its  cyrus.conf(5)  services  entry.
       prefork=1 is also recommended.

       notifyd reads its configuration options out of the imapd.conf(5) file unless specified otherwise by -C.

       notifysocket option is used to specify the Unix domain socket to listen on for notifications.

       /etc/imapd.conf, /etc/cyrus.conf

       Cyrus notification server

null
          Ignore the notification request.

       log
          Log the notification to syslog (for testing).

       mailto
          Email  the  notification.   This  method  can ONLY be used in a Sieve 'notify' action as it requires a
          mailto: URL to be specified as an :option.

       zephyr
          Send the notification as a zephyrgram.  If used in a Sieve 'notify' action, additional recipients  can
          be specified as :options.

       external
          Send  the  notification  via  an  external  program.   The  path to the program is specified using the
          notify_external option in the configuration file.

-Cconfig-file
              Use the specified configuration file config-file rather than the default imapd.conf(5).

       -Uuses
              The  maximum  number  of times that the process should be used for new connections before shutting
              down.  The default is 250.

       -Ttimeout
              The number of seconds that the process will wait for a new connection before shutting down.   Note
              that a value of 0 (zero) will disable the timeout.  The default is 60.

       -D     Run external debugger specified in debug_command.
