BTW here is the error message: IMAP Banner Reverse DNS Check:Failed - IMAP Banner/Greeting Does not contain your hostname The email checker service is https://www.unlocktheinbox.com/ in the event the topic crops up again. I hadn't noticed it was an imap issue, so mkaybe this should have been a dovecot question. But in any event, if the banner isn't really required, the question is answered. I will admit the "unlocktheinbox" service is very complete, though prone to false postives unless you read the report carefully. (Hint: look for the word obsolete.) In my internet search, I ran into one document that suggested not to use the smtp banner since it gives a clue (albeit minor in my opinion) about the email server. You could probably learn more from a bounced email.
