The SMTP-POP3/IMAP task provides complete end-to-end monitoring of your Mail servers. First a monitoring agent tests the SMTP server by sending an e-mail to the specified e-mail address. After that e-mail is sent the agent attempts to log in and retrieve the e-mail from a POP3/IMAP server. If the SMTP or POP3/IMAP steps experience an error or the email is not found within a specified time-out period an error is recorded. If you have alerts configured, you will receive an alert.
