Hmmm.. this sounds like a tricky one

If you are getting the headers correctly, then we know it's talking to the INN server correctly and understands how to retrieve header information by message number.

The next thing the script does is to run those headers through the spam filter and if it decides it's an article we want, it requests the body from the news server using the message number and the 'body()' method from perl NNTP module. Assuming you have no replacements set, this must be the bit that is failing to retrieve the article from the server.

Why it's failing, I have no idea. Have you got another news server you can try. That way you can determine if it's an INN specific thing. You might want to make sure you have the latest NNTP module from CPAN aswell.
