We have an email forward
email@example.com that goes to a client's personal email address which is not on that server or domain. The client received a "did not deliver" notification addressed to
firstname.lastname@example.org, and they said they were not the ones that sent this email that was never delivered. Here is the content of the notification email:
This message was created automatically by mail delivery software. A message that you sent has not yet been delivered to one or more of its recipients after more than 720 hours on the queue on otherserver.com. The message identifier is: 1VAhiC-0003UW-KY The subject of the message is: How to Get Skinny The date of the message is: Sat, 17 Aug 2013 11:34:15 -0200 The address to which the message has not yet been delivered is: save to /home/izs/imap/otherserver/info/Maildir/.INBOX.spam/new/ generated by email@example.com 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.
We're not associated with
otherdomain.com. As far as I know, it's impossible for
firstname.lastname@example.org to send this email because it's only a forward.
Can someone please explain to me how this may have happened, and ways to fix it?
We're using shared hosting on Bluehost if that's relevant.
