Hi,

I am getting a lot of spam mails from spammer misusing (faking) my email address and sending spam mails (not through my server).

Those spam mails bounce and get sent back to my email address.

Xeams will often let these kind of mails through. Is there anyway I can filter this or can anyone give me a hint on how to setup Xeams to treat these messages as spam ?

Thanks!

Oliver,

What you're referring is called a Reverse NDR attack. Click here for details. If you like you can block NDRs temporarily until this is over by enabling the Non-Delivery Report filter under Filter Management/Content Filters/Custom Filters.

thanks for the reply.

What I don't understand is: The email server is a closed relay. Only authenticated users are allowed to send emails.

So the sent emails have an existing email address (although faked) and are sent through a email server somewhere in the world.

If those emails get rejected, why is the NDR being sent to me (the existing email address) ? And why can't Xeams recognize this and treat it as Spam ?

Thanks again
