paulp Posted May 21, 2008 Share Posted May 21, 2008 Hello, our domain 184.108.40.206 has been listed in bl.spamcop.net (127.0.0.2). I wrote to the deputies in order to find out what has happened and they sent me a copy of the offending mail. This helped me to search the logs and find what has happened: A spammer, using a Spamcop spamtrap address as a fake sender address, sends 10 mails to our domain. 7 of them are sent to non existing addresses and they are refused immediately, without a bounce message. 3 of them are sent to legitimate addresses and are delivered. One of these three users has installed a forwarding to his home address. When the spam mail reaches the mail server of his home address, this server refuses, and sends a 554 message with the text "Mail contains a URL listed on www.surbl.org" to my mail server 220.127.116.11. This mail server notifies the sender (= the spamtrap) of the non delivery, and our domain gets on the blacklist. The Spamcop deputy does not want to delist us, because "this is accept-and-bounce and accept-and-bounce is bad". Is this really an accept-and-bounce case? What do you do if a mail gets refused before delivery? The sender somehow has to know that his mail was refused. Most practically it would be to notify the sender only if it is a known account, but in my mail server program (Mailtraq) I cannot find a way to do this. Any thoughts? Thanks!
