Hi Ferrell,
Its called "backscatter". I had to post some info about it on my site for my own clients. Feel free to copy it. http://www.123marbella.net/kb.html#6 I am currently looking at alligate gateway in order to add some added protection to my mail network. However, declude does have a filter for this and i did install it and no one has really complained since then so it may have worked. Kindest Regards Craig Edmonds 123 Marbella Internet W: www.123marbella.com From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ferrell Ard Sent: 22 April 2008 17:22 To: declude.junkmail@declude.com Subject: Re: [Declude.JunkMail] SPAMMERS using "postmaster@<domain>" in their FROM email Importance: High Don't know if Declude (or anyone) can help, but we are seeing a L O T of bounce-backs that show that the SPAMMERS are using valid postmaster@ <mailto:[EMAIL PROTECTED]> <domain> (that we host) as their FROM address and send the SPAM out thru Post Offices other than ours. When the SPAM goes to a non-existant address, it bounces back to the valid postmaster@ <mailto:[EMAIL PROTECTED]> <domain> on my Server. We are getting 5,000 - 10,000 of these bounces per day.. Any suggestions? Thanks very much Ferrell --- This E-mail came from the Declude.JunkMail mailing list.
