Forged Spam Headers Causing Spam Problems

Recently we have noticed that Postini has been having some difficulties with a particular type of image spam. In the email headers there seems to be a forged X-Spamshield-Status-DATA header listing: Skipped, authenticated user.

These messages also all seem to contain an unusual unsubscribe message at the bottom of the email. Instead of the typical Unsubscribe link it is an image:

Until anti-spam vendors get signatures in place to stop this spam, we are recommending that putting a content filter in place either on your anti-spam solution or on your mailbox to move messages with the “X-Spamshield-Status-DATA: Skipped, authenticated user” header to Junk.

We do not recommend clicking the image or trying to unsubscribe to these messages as you will just validate your email for spammers.

    Joke,

    Sorry to hear that you are having blacklist troubles. You can follow the links to the Blacklist websites (via the “details” link or the Blacklist name) and request delisting directly from them.

    I also want to provide you with a link to a very handy article we posted on our blog – What Blacklists Are and How MxToolbox Helps: http://community.mxtoolbox.com/blog/2009/03/04/what-blacklists-are-and-how-mxtoolbox-helps/! The article will explain a lot about how our services eliminate the problems blacklists cause and how they are oftentimes recurring and hard to permanently fix.

    If you can’t get resolution to the problems, don’t hesitate to call or e-mail me and we can discuss the problems further. Thank you!!
