Email Monitoring - SMTP/POP3/IMAP

SMTP Monitoring Service

SMTP Simple Mail Transfer Protocol (SMTP), the Internet protocol for electronic mail delivery. Most mail servers today use this protocol to deliver and receive e-mail.

Whenever you send a piece of e-mail, your e-mail client interacts with the SMTP server to handle the sending. The SMTP server on your host may have conversations with other SMTP servers to actually deliver the e-mail. Our agents monitor the SMTP server by connecting to specified mail server and doing an SMTP handshake. If a remote server does not respond to a handshake or is unavailable you will receive notification from Dotcom-Monitor^®.

POP / IMAP Monitoring Service

Post Office Protocol version 3 (POP3) monitoring. Our remote network monitoring agents use a protocol similar to checking e-mail to monitor POP3 servers. Dotcom-Monitor^® connects to mail server (POP3 server) and logs in using a user name and password you provide. For example, when you check your e-mail your e-mail client connects to a POP3 server using port 110. The POP3 server requires an account name and a password. Once you have logged into the POP3 server it opens your text file and allows you to access it. Dotcom-Monitor^® uses the same protocol to monitor your POP3 servers.

SMTP - POP3/IMAP Monitoring Service

This task allows complete end-to-end monitoring of your Mail servers. First we test the SMTP server by sending an e-mail to a designated e-mail address. Then after that e-mail is sent Dotcom-Monitor^® attempts to retrieve an e-mail that we send from a POP3 server. If the SMTP or POP3 processes fail or mail is not found within a specified time-out period you will receive a notification from Dotcom-Monitor^®.
