MailFlow Monitoring

Our Engineers specifically built this one of a kind tool that allows you to truly monitor your mail server. This tools goes beyond just monitoring SMTP, it provides real-time daily, weekly and/or monthly statistics by monitoring the status of all mail in and out of your server. Our system sends a message to your server every 5 minutes, to which your system auto-replies or sends a forward back to us. This allows you to get a true picture of the Up/Down status and performance of your mail-server!

Local Server Settings

There are two ways to configure the MailFlow monitor on your server, the first way is quick and easy and will alert you if your Mail Transfer Agent (MTA) is down. The second way is considered a bit more advanced and includes a few extra steps. The majority of users will find success with the first setup and only should use the second setup if they have concerns about receiving alerts if the Mail Store was down as well.

Tips for setting up your forwarding rule:
  • If you are setting up multiple monitors to test different mailflow paths, you can use the same mailbox more than once to do the forwards. In this case, you would use the same email address when writing the monitor command, but different IP addresses
  • While setting up your monitor, a good troubleshooting setup is to check the mailbox on your end to make sure our test messages are reaching you.
