Strange problem with posting on Inn2.2.2

[Mauro Clementi]

Hi everybody.

I am currently testing my Inn 2.2.2 installation under solaris 2.7
environment.
I have to deal with the following (strange) problem.

If I use a Netscape client to post an article, the posting goes ok.
If I try to post with Outlook or making a telnet on the 119 port, I
receive the message

441 435 Bad Message-ID.

Every other thing seems to be working. I receive articles and store them
in cnfs storage (seemingly) without problems, and the colleague working
on the feeder told me that he is
receiving my posting (ok, at this moment I am the only one that posts
articles, and I use netscape....I had to try to post with Outlook to
know that I had some problems....),

I'm currently reading the RFC977 (NNTP) just to find the exact meaning
of the error
code I received, but I found no more that the canonical explanations:

441 Posting failed

435 Article not wanted, do not send it

I would like to know if there is something misconfigured (ok, I think
so...), and
how can I activate any debug capability of Inn

Thank you very much in advance

I can give deeper level of details if anyone wants to know more.
