Thanks. I have emailed him.

Thanks guys. [at]SpamCopAdmin Is there anyway you could PM me from which email address the spam originated from so I can investigate on my side. When I look at the mail logs of the server, I don't see any abnormal activity. Or perhaps send me a timestamp of when such an email hit a spamtrap, so I can have a closer look. The system is being used by a conveyancing firm and they do have an app locally that relays mail through our server, where I think the spam could originate from. For your assistance I thank you in advance.

Hi we are getting a bounce back messages from recipients mail server. They all claim that our IP's are listed in the spamcop list, yet, they are not listed, or each time we do a lookup they are not listed. Please could someone share some light on this..
