Monitoring mail servers

The Email monitor lets you monitor that a mail server is available and functioning correctly.

Note: This feature is available with WhatsUp Gold Premium, ProView, TotalView, and TotalView Plus Editions only. To update your license, visit the WhatsUp Customer Portal.

This monitor checks a mail server by first sending the server an email via SMTP. The monitor then attempts to delete previously sent emails using either POP3 or IMAP. If no emails from the monitor are present in the inbox to delete, the mail server is considered down.

The Email active monitor supports encryption with SSL/TLS and SMTP Authentication which ensures that the monitor sends emails to a secure email account.

The Email monitor's email delivery check is done across two polls. Therefore, it is important that you pick a meaningful polling interval. For example, if you want to be notified when your mail server is taking more than two minutes to send and receive email, use a two-minute polling interval.

Note: WhatsUp Gold can monitor any POP3 server that supports these commands: USER, PASS, LIST, TOP, QUIT, RETR, and DELE. WhatsUp Gold can monitor any IMAP server that supports these commands: LOGIN, SELECT, SEARCH, STORE, CLOSE, and LOGOUT.
