Each time I try to send an email I get a message saying spamcop is blocking my email. Here is the message. Not that I removed the recipients ID An error occurred while sending mail. The mail server responded: Blocked - see http://www.spamcop.net/bl.shtml?18.104.22.168. Please check the message recipient *******[at]yahoo.com and try again. I tried resolving this by requesting the address by delisted and I recieved confirmation that it was. If I query the spamcop database it says the ip address is not listed but I am still blocked when I try to send an email.
