Mail delivery failed: returning message to sender
Hello my friend
Mail delivery failed: returning message to sender errors are generally encountered when an intended recipient does not exist on the remote server.
You will normally receive a bounceback message with this error in the subject, and the body of the message should contain the original message that was attempting to be sent.

Resolving Mail delivery failed: returning message to sender bounce-backs
Typically these type of bounceback errors are hard bounces meaning that trying to send the message again won't be successful. You can read our previous article on why does email bounce, bounceback, or error? for a more in-depth explanation of a hard bounce.
In the particular bounce-back example above, the cause of the issue is that this user has WordPress setup to allow comments on posts. A spammer attempted to leave a comment on one of their posts, and the WordPress administrator of this site has setup their e-mail account as recipient@RemoteDomain.com. So that is theaddress used to send comment moderation requests to. However that e-mail address doesn't exist on the RemoteDomain.com mail server, so it's always going to fail and cause a bounce-back error.
If you happen to also be having issues with WordPress comment spam causing bounce-back errors for your account, we have an advanced article on WordPress comment spam clean up that could help you clear this issue up.
