SPAMCOP IS BLOCKING EMAILS

Numerous emails being returned from Spamcop.  They're reporting as spam.   
Someone else I see has posted this in the questions forum, but i wanted to report this as a problem.   It was sporadic last week but I could get some through if i waited and resent the email.  But as of yesterday none of my resent emails are going thru. They're all being blocked by spamcop.
