I changed over from Spam Arrest, which I wasn't completely happy with to SpamCop. I set it up and it seemed to be working. Then I went to bed and woke up to find I had no emails. Strange. I get many. I got a Skype message from an associate that my emails had been bouncing back to him. I heard from others who told me the same thing. So I went back to Spam Arrest and emailed SpamCop with my issue. No reply. I emailed them 3 times. Still no reply. Now it's a week later. I have twice emailed asking for a refund and still no reply. This service sucks!
