Email delivery may fail for several reasons, especially in a modern corporate environment containing spam filters and firewalls. ipMonitor Administrators can configure all related settings in order to ensure that emailed Alerts and Reports are sent appropriately.
ipMonitor attempts to deliver email by following these steps:
- ipMonitor attempts to connect to
domain.com 25 (where domain.com is the email recipient's domain, and 25 is the port).
- If the connection is successful, the email message is sent.
- If the connection is unsuccessful, ipMonitor connects to the DNS server to look up the preferred MX record for the recipient's domain.
- ipMonitor attempts to connect to the MX record on port 25.
- If the MX record connection is successful, the email message is sent.
- If the MX record connection is unsuccessful, ipMonitor attempts to connect to the next listed MX record, if one exists. Otherwise, the email cannot be sent.
You can bypass this trial-and-error email delivery process if you specify an SMTP mail server for ipMonitor to use. In the event that your specified mail server is unreachable, ipMonitor will revert to using the trial-and-error steps outlined above.
To specify an SMTP mail server for ipMonitor
- Log in to the ipMonitor web console.
- Click the Configuration tab.
