It may be a header that Pan is adding, but again, you have to ask the 
posting provider for the details because only they know what's in their 
post filter.  I've run NNTP servers on more than a few occasions, and I 
can tell you definitively that the "441 Posting Failed (Rejected by POST 
filter)" means that it's something being filtered by the provider - and 
*only* the provider can give you more specifics.

We could guess, but it would be nothing but a guess.  Post filters on the 
systems that I've worked on are perl scripts and can filter on anything 
in the headers or the body of the message.  There is no way to know what 
specifically that provider has put in their filter without asking them or 
experimenting.

It may be as simple as they've blocked posts where the NNTP-Posting-Agent 
isn't one of a set list of allowed clients, or where it excludes Pan 
explicitly for some reason.  Or it could be that it doesn't like the 
format of the NNTP-Posting-Date header.  Or under "More Headers" you 
could have a header in there that they want to reject.

I've written post filters myself, and I've excluded based on e-mail 
address, posting agent, IP address range, and words in the body text.  It 
really can be anything.  You have to ask the provider to help you 
diagnose it.
