To further debug the problem, Russ and others asked for a sample of a
failing message header. I modified my mailagent filter to save a raw copy
of the email message in a file. The message is then sent through my perl
filter to fix potential header problems, a second copy of the modified
message is then saved, and finally it is fed to inews. This particular
email is "spam" and is intended to be posted to a junk newsgroup where it
can later be quickly revived and disposed of.
As usual, this is the error message:
inews: cannot send article to server: 441 Invalid syntax encountered in
headers
(unexpected byte, no colon-space, or empty content line)
inews: article not posted

Here is the original message header (body deleted):

Notes on the header modifications:
1: The filter is used on all messages and most do post.
2: The Received: headers are converted to X-Rec##: because I wanted
inn2 to retain them. Unfortunately, it still deletes them when
posting. (Is there a way to control which headers inn2 will retain?)
3: Note that the DKIM-Signature: header was deleted as it was too long
for inn2 and long headers were causing posting rejection.
4: Header continuation lines are coming in with spaces at the beginning
of the lines. All leading whitespace is converted to a <tab>.
5: If missing, an Approved: and Lines: header are added to the end of
the header block.
6: Unless I'm blind, there are no empty headers or unusual characters
anywhere.

/usr/bin/rnews points to usr/lib/news/bin/rnews which is:
-rwsr-xr-- 1 news uucp 22640 Dec 29 16:21 /usr/lib/news/bin/rnews
I cannot execute this as a normal user with the given permissions. Any
comments on that? I could change the permissions so that my mailagent
utility could then access it, but I'm asuming that this is set this way
for a reason.

I do really appreciate all the help that is being offered and look forward
to continuing this discussion and getting to the bottom of the problem.

Thanks! Here's your problem:

Three empty headers.
We probably could, with some work, make INN more tolerant of these, since
they shouldn't interfere with the rest of INN's processing as long as
they're not included in overview, but they're definitely syntactically
invalid.
A better fix would probably be to change the program doing the message
posting, or your Perl filter, to look for empty headers like this and
change them to something like:
X-Broken-Header: X-Source:
(which is what the News::Article Perl module does).

rnews is setuid for historic reasons related to its original purpose of
processing UUCP news batches. It's totally unnecessary on systems that
don't process UUCP batches, and is no longer the default configuration.
You could probably just use dpkg-statoverride (I think this is a Debian
system or variant?) to change the mode to 755.
