Why does this spam look like I sent it?
Posted on 22 November 2003 07:24 AM
It is possible that you will receive an email at some point in time that has your own email address in the From: field, and yet you know you did not send it! Or you may receive a bounce message for failed delivery, where the message which was bounced appears to have been sent by you, and yet you know you did not send the original message.

How can this happen?

It is trivial for someone to forge the From: field in an email message, and therefore the From: field of an email message does not necessarily indicate the true source of the email. Someone with the proper knowledge or software, such as a spammer or virus author, could quite easily forge the From: field of an email.

The sender does not require access to your account or your mail server to send out email with your email address forged in the From field. An inspection of the email headers should reveal the source of the email and whether it was sent through the FutureQuest® servers or not.

In most cases, you can disregard these emails. They are either the result of a virus, or just a common spam. However, if you are the victim of a Joe Job (i.e., a large spam run that has been sent out forged to make it look like you sent it), you should investigate and report the source. Also, address any possible complaints, and post disclaimers and notices on your web site to alert recipients of the spam to what has actually happened.
