Your message could not be delivered to some or all of the intended recipients.

From: [email-masked]
Recipient(s): [email-masked]
Reason: 550 5.1.1 User unknown

By RFC 2821, chapter 3.7 <http://rfc.net/rfc2821.html#s3.7>we are required to send these non-delivery-reports. In the case you are not the sender of this message, your address has been used by spammers to send out mass-mail.

<Copied from the above RFC>
If an SMTP server has accepted the task of relaying the mail and later finds that the destination is incorrect or that the mail cannot be delivered for some other reason, then it MUST construct an "undeliverable mail" notification message and send it to the originator of the undeliverable mail (as indicated by the reverse-path).
