I shared this conversation yesterday with support of Mailgun.com. I got an immediate reply that they are investigating the case. Today i see that all is fine. None of the ip's 141.193.32.12, 141.193.32.19, 141.193.32.22, 141.193.32.23, 141.193.32.26 and my ip 141.193.32.22.10 at Mailgun are listed anymore by Spamcop. I thank Mailgun and Spamcop for their great response.

Thanks for your quick reply. I will contact my ISP (Mailgun.com) to see what they can do. However, it is curious that about 50% of the messages from the same host to that same email address are not blocked.

Today i wanted to report a uncorrect block of my domain. Count not get past the captcha after 3 trials.

My domain is blocked because of spam activity of 5 neighboring ip addresses. My ISP shares a system for multiple accounts on a single host. This is common practice for low cost services. My ip is 141.193.32.10. The suspected spammers have ip addresses 141.193.32.12, 141.193.32.19, 141.193.32.22, 141.193.32.23, 141.193.32.26. They share the same 3 octets but have nothing to do with my account. Can SPAMCOP please stop this practice!
