   1. Service description: Here you can type in a service description. Please make sure that this is unique per host and does not collide with other services.

   3. Forward mails as events to Event Console.
      

      1. Forwarding Method: Here you can select if you want to send the events either to the EC or to a remote syslog host. If you want to send the events to the local EC, we would recommend using the spooling mechanism.
         By using the spooling mechanism, the check will store all collected eventsin one file in ~/var/mkeventd/spool.

      2. Only process mails with matching subject: Use this option to not process all messages found in the inbox, but only the those whose subject matches the given regular expression. The text entered here is handled as a regular expression pattern. The pattern is matched from the beginning. Add a tailing $ to change it to a whole text match. The match is performed case sensitive. Read more about regular expression matching in Checkmk in our user manual.
         
         

      3. Events: Syslog facility: Use this syslog facility for all created events
         
         

      4. Events: Hostname: Use this hostname for all created events instead of the name of the mailserver
         
         

      5. Limit length of mail body: When forwarding mails from the mailbox to the event console, the body of the mail is limited to the given number of characters.
         
         

      6. Cleanup messages: The handled messages (see subject matching) can be cleaned up by either deleting them or moving them to a subfolder. By default nothing is cleaned up.
