I checked with my host. They told me that 180 of their customers share that IP address to send emails and that apparently one of those 180 people had sent something which the recipients classified as spam. But a technician apparently had already contacted spamcop, to have the IP address removed from the block list.
And in fact yesterday evening the IP address was no longer in Spamcop's block list, but hours after I had checked, another email bounced back. I checked again with spamcop and the IP address was not in the block list. My guess is that the email provider of the recipient had not updated yet their block list.
Now I have a strange feeling, because over the past three weeks or so I have received emails from potential customers but (almost) no replies to my reply. Could it be that the IP address of my mailserver has been blacklisted over that period?
And, most important, when you send an email and it gets blocked by the mailserver of a mail provider/host for spam reasons, do you get notified about this?
By the way, I'm using spamcop myself and report now and then spam.

It's hard to say. Some of my colleagues read my emails but rarely reply. It's very possible that your email could have been deleted by the recipients spam filter without any type of acknowledgement by the sender. I know that some services that use spam assasin just assume that everything with a score of 5 is spam and send the spam into the bitbucket never to be heard from again. While most email with a spam assasin score over 5 is spam it isn't uncommon to have false positives at that level. It is even worse for people that rely soley on blacklists such as spamcop since it only takes one person abusing the same mail server to get you blacklisted for a while.
In all likelyhood if your email got blocked you probably wouldn't have gotten a "refused by spamcop" bounce since I think most administrators don't bother with that anymore since most spamcop bounce messages won't get read by anyone anyway. I would probably assume that some of your email got blocked while your mail server was on the blacklist.
