Hey Guys, We run multiple mail servers and have been very pro-active in fighting spam. When spam is reported to be sent from one of our customers, we investigate the issue and either terminate the account or educate the user (we had a case where a good honest customer bought a mailing list and sent out one mailing. After we warned him, it never repeated). And BTW, we use Spamcop on our own system to block incoming junk mail. Recently one of our mail systems 18.104.22.168 was blocked by Spamcop. My concern was that there was no reason listed for the blockage on the page, http://www.spamcop.net/w3m?action=blcheck&ip=22.214.171.124 Upon checking it by looking at the TXT record returned from 126.96.36.199.bl.spamcop.net, i get ""Blocked - see http://www.spamcop.net/bl.shtml?188.8.131.52". Any how, I would greatly appreciate if someone could help me figure out the reason for the blockage. Possible removal would be nice as well :-) Thanks in advance.
