"If spamcop saw it (ie, the mail was directed through the spamcop configuration, then there will be a set of headers starting x-spamcop-* and x-spam-* that were added.   \n\nIf those extra headers are not there, then perhaps you are still popping messages directly from your ISP before spamcop cna POP them?  Another option is if both accounts are on the same server, they might never have traveled on the internet to access spamcop.  I don't know your configuration to be able to answer any better. \n"
