  1. Hi, About three weeks ago, a few people trying to email me said that they were getting bounces back that their messages were undeliverable. The message bounce said that SpamCop had blacklisted the address or domain. However, I can't find any way that SpamCop is even associated with me. My ISP and domain host are also completely baffled how SC could be blocking these messages. Anyone know how to trace this? Thanks! Here's the error message: The following addresses had permanent fatal errors ----- <casey[at]compelling-cases.com> (reason: 550-Message rejected because mail.cybermesa.com [] is blacklisted) ----- Transcript of session follows ----- ... while talking to mail.compelling-cases.com.: >>> DATA <<< 550-Message rejected because mail.cybermesa.com [] is blacklisted <<< 550 at bl.spamcop.net see Blocked - see http://www.spamcop.net/bl.shtml? 550 5.1.1 <casey[at]compelling-cases.com>...
