Using blacklists to fight spam is a really dull instrument. The risk of false positives when blacklisting domains as gmail.com or yahoo.com (or collab.net for that matter) is obvious. Make a google search for spamcop and I think you will find more people having touble. See for example:

I suggest you re-configure your mail system not to reject mails purely based on such loose grounds as a third party blacklist.
