Two questions ... first, what is the [11498] in the log file:

Mar  8 20:43:03 news nnrpd[11498]: SERVER perl filtering enabled

I would have thought it was PID, but if I do a grep for, say, 3277 in the log file, it doesn't return anything:

%grep 3277 /var/log/news/news.notice
%

Next question ... how do you disable the PERL filtering in nnrpd?  I don't 
find a switch in etc/inn.conf ... just figured I'd disable it and see if 
maybe *it* is somehow affecting things ...
