Security Issue?
Hi Guys,

Need a little help with an issue I *think* we're having. Im getting alot of returned emails, an example below..

Your message did not reach some or all of the intended recipients.

Subject: Naked Shakira Clip
Sent: 26/03/2008 07:23

The following recipient(s) could not be reached:

charles@whatcomsoccer.com on 26/03/2008 10:12
The e-mail account does not exist at the organization this message was sent to. Check the e-mail address, or contact the recipient directly to find out the correct address.
< mx1.hardlines.com #5.1.1 SMTP; 550 5.1.1 User unknown>

Im wondering if somehow these are being sent from us? Perhaps a virus of some sort? I really have no experience in this area!!

Cheers

Fergal is spot on. It is almost certainly someone spoofing your address. Quite common - I've been seeing this for some years.

A closer look at the headers should make this obvious.

There is very little that can be done about it.

Harry.

You will find that this happens in batches. After a few days the bounces will die down as the spammer will someone else's address.

A suggestion is to ‘remind’ your users of this type of spam tactic and make sure they don’t open any emails and/or attachments they don’t recognize. Reference a specific clause in the employee handbook or other organizational document if possible.

Sounds simple, but it’s amazing how many folks will open an attachment in an email that looks to have bounced back, but they never sent in the first place.
