Hi, I run my own small email server for my home network using sendmail (fully patched), I have set it up to deny relaying for another domain apart from my own, just lately I've been getting a lot of spam from China and Taiwan, most are forging the from address (naturally), below are some examples:
The weird one just arrived yesterday, they sent it to a non valid account, in my virtusertable, I have specified anything else that doesn't match the listed names, send back an error msg, yet these one got through. [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] There are around a another 50 bogus accounts supplied in the To field, all to [EMAIL PROTECTED], this has been automated by some script. What I'm having problems working out is how can they manage to get through, when not a single email address is valid, testing one of these addresses from either home or work, all report back an error to me and the mail isn't sent. I know I can put a few rules on the firewall to stop the IP or domain, but does anyone know of a way in sendmail that I could stop this happening without resorting to using say procmail Cheers Mark -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
