Hi, i have a problem with stopping spams. The situation is this. Spammers are using our domains to send spam to us. This is one of the example:
Let's think that one of the our domains is mydomain1.com and [EMAIL PROTECTED] is real user in our system. The spammers send me mail this way: HELO spammer.com MAIL FROM:<[EMAIL PROTECTED]> RCPT TO:<[EMAIL PROTECTED]> DATA this is a spam . RSET QUIT This is the scenario that spammers use to send spams to my users. What i want to do is to stop spammers to send me this way spam to my users. Is there some way to block this way, or to set some kind of authentication only if in MAIL FROM: field they use our domains? How can i solve this problem at all? Thanks in advanced! Regards, Ali Nebi!
