How can I perform a round-trip check of an email?
1. Create a SMTP Watch Item that sends a message to an email account that is specifically for testing. For verification, the email sent should contain text that will be searched on when downloaded.
2. Create a POP3 Watch Item that retrieves email from the test email account, and searches for the text included in the message.
3. Link the two together by putting them in a Transaction and order them so that the SMTP Watch Item runs first, and the POP3 Watch Item runs second. If one or both fail, the transaction will fail and an alarm can be triggered.
