Mail Server Monitoring

Detect Mail Server Problems

The basis of email infrastructure is mostly SMTP servers for sending and IMAP or POP3 servers for receiving. If a server fails, emails can no longer be sent or received.

The SMTP, IMAP and POP3 monitors connect to the server and query its status. If a server does not signal any readiness to send or receive, you will be alerted immediately.

Ensure Email Sending/Receiving

Errors in email infrastructure can occur in many different places. The ultimate function test is sending an email and checking whether it has arrived.

This is exactly what the EMAIL Monitor does completely automatically. If an email is not delivered within the specified time, you will receive a notification.

Do you send spam?

As soon as your domain (e.g. is listed on an email blacklist, your emails will most likely end up in the recipient’s spam folder. Unfortunately, domains that do not send spam are also often included on the blacklists. This may be due to the fact that spam was sent via the provider’s server that is also used to send your emails or that a recipient incorrectly reported the domain as a spam sender.

The Blacklist Monitor regularly checks the major blacklists to see if your domain is listed.
