[Scspamcop] Spam list issue (we can't send email to our customer)

[william]

Dear Sir,

We still received the below message from spamcop, however, our company IP
(202.76.106.125) is not listing in your spam list. Please let me know how to
solve it.

Error:

[pc125.solomon-systech.com] blocked by bl.spamcop.net; 202.76.106.125
