as someone pointed out, I just needed to add '!*,' before the
group name.

Hmm I did diff on the sources, patched the appropriate line in my
news2mail but it is still happening.

I think it is perhaps the part where it was added is SKIPPING not 
STRIPPING those headers. (at least it is what the comment says)

                #
                # skip unnecessary headers
                #
                next if ($line =~ /^NNTP-Posting-Date:/i);
                next if ($line =~ /^NNTP-Posting-Host:/i);
                next if ($line =~ /^X-Trace:/i);
                next if ($line =~ /^Xref:/i);
                next if ($line =~ /^Path:/i);
