The requirements for message ID's for Usenet posts are more strict than
they are for email messages . Check out
<http://www.faqs.org/rfcs/rfc1036.html> section 2.1.5. Sounds like Opera
is not generating a valid message ID.

As for what you can do about it, I'm not sure. I believe that Opera will
generate the message ID based on the host name of the posting host. You
could try making sure that the host has a reasonable name set.

Sorry I can't be more help.
