Thank you for your answers. I do work on One.com. All reports are investigated and the report 5669978731 was for an spamming account we had suspended. The time for this report corresponds with when the server got blacklisted the second time. But that would mean that this single human report caused the block. For the first time spamtrap hit seems to be a plausible explanation. Hopefully this can be confirmed by Spamcop soon.

On of our mail servers, 195.47.247.21, was blocked on Sunday but got unblocked again before we had time to investigate. We can not see that any mail has been sent with details about the spam complaints. We only received a short mail when the server was blocked, and one when the server was unblocked. On Monday I used http://www.spamcop.net/fom-serve/cache/91.html to ask Spamcop for more information, but I have not got any reply yet. Yesterday the IP number got blocked again for some hours, that time we got a mail with details. But I don't see why one single spam complaint should cause us to be blocked (especially since the spamming account already was suspended). Do you have any suggestion what I should do now or what might cause the missing Spamcop mails?
