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 the address 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.

Hi,

   Thank you for the suggestions.  I had tried "add that particular address to the blocked list", but it didn't work.  I've resolved the problem now.  It was a scorpion virus. I had to pay Norton $99 to uninstall/reinstall Norton antivirus and change my password. 

   Again, thank you for your suggestion.

Hello Jorunn,

Thank you for your question. The content of this email message is being flagges bu Google as spam.

The link you provided, included more in-depth information from Google.

I recommend avoiding common words that trigger spam filters.

Also, SPF records and Domain Keys can verify your emails are being sent un-tampered from a valid server.

Thank you,
John-Paul

it seems that your local IP address 198.1.82.190 does not have a valid reverse DNS in which your mail has been authenticating.

So kindly contact your local internet provider to add the valid reverse DNS else try with any other internet provider.

Hello saravananct,

Thank you for contacting us. Since we do not own that IP address we cannot setup the reverse DNS for you. I recommend contacting your host, so they can assist you with this configuration.

Hello Roy,
Sorry for continuing problems with the email. I looked at the history of the account, and there was previous problems with queued items with ntelos. com. Though this was noted 13 days ago, there still appears to be an issue with sending mail to Ntelos . I tried with a test from the server and this is message I immediately received:

R=lookuphost T=remote_smtp: retry time not reached for any host after a long failure period

I highly suggest speaking with Ntelos to see what's going on. We can provide the error messages if necessary (though the main one is the one I've shown). This will require the attention of the Ntelos email administrator. Please contact them with the information you have provided and see if it is possible to clear the queued items, or if there is another problem.

Apologies again for the problem with the email. If you have any further questions or comments, please let us know.

Regards,
Arnel C.

That is correct. When there is an error in mail delivery service it is normal to see a bounce-back message like this. These messages tell you why the mail delivery didn't work.

Since the second message mentions your DKIM record, ensure you have setup SPF Records and Domain Keys (DKIM) for your domain.

I also recommend setting up DMARC records. This allows you to specify how mail servers should handle messages from your domain that do not have valid SPF and DKIM records setup. Since the DMARC standard is used by many email providers (such as Gmail, Yahoo, AOL, Hotmail, Outlook), it can increase your chances of email being delivered successfully.

That email account is disabled. You will not be able to send emails to a disabled account. If you have another way to contact that account owner they may want to know their account is disabled.

Can you please explain this message.  I have been trying to track down this problem for awhile.  It happens to several people randomly.  I'm thinking it's in our network. 

Thanks.

No action is required on your part. Delivery attempts will continue for some time, and this warning may be repeated at intervals if the message remains undelivered. Eventually the mail delivery software will give up, and when that happens, the message will be returned to you.

You will want to contact the Live Support team so they can look into this for you. They should be able to see if your server is sending the emails or you are merely being spoofed. They will have a method of correction either way so you can help prevent this from continuing.

A failed address message is typically due to a misspelling of the address, an address that has not been created yet or the recipient server is experiencing an issue.

Thank you,
