Spamcop listings are based on detected spam.
Non-repeat offenders normally are delisted after
24 hours of non-activity.  (See the FAQ for more
precise details.)  If you're an admin for your domain
(i.e. have access to postmaster, etc.) you can
contact deputies at spamcop.net to see what's
causing you to be listed.

However, as you say, the problem may not have
anything to do with spamcop at all.  If you have a
configuration problem and are an open relay,
presumably that isn't coming and going.  :)

Usually mailers only send out a response when
you're actually blocked (i.e. it blocks a message).
If that's not what your question meant, another
answer may be: yes, it is indeed easy to
misconfigure a mail server program to blame one
block for another.

To paraphrase Mike Easter, people here could tell
you more if you gave the IP addr in question.

Hope that helps.
