I am using some network monitoring software 'PRTG' to monitor the health of my mail server. Rules have setup are as follows:
- Notify me when connection is down.
- Notify me when the mail server is greylisted.
- Notify me when the mail server is blacklisted.
- Notify me if >1000 emails get send out in a 5 minute period.
- Notify me DNS on the mail server fails.
Is their anything I should be checking for?
Any suggestions are welcome.
