Any way to stop spammers from forging the "From" or "Reply To" fields?
Posted by mifbody, 03-28-2008, 07:21 PM Hey guys, Is there any possible way to stop spammers from forging my website's domain in the "From" or "Reply To" fields? I just received 1700 bounced e-mails in my inbox from spammers using my domain in the "From" address. Really freaking annoying, and I don't want my website to get blacklisted.

Posted by marcbarak, 03-28-2008, 08:09 PM I would highly suggest add a txt record in your nameservers (EX: "v=spf1 a mx ~all") A query will show the legitimacy of your SMTP client IP.
Posted by mifbody, 03-28-2008, 08:42 PM That's the worst part -- I have the SPF and the domainkeys installed and still get 1700 some bounce-backs.
Posted by marcbarak, 03-28-2008, 09:18 PM The SPF only shows emails sent from your IP are legitimate - so a frustrated ISP looking back sees it is not you and does not blacklist you There is no way to stop anyone from creating false headers UNFORTUNATELY
