Finding Message IDs of Rejected Messages?

[Felix E. Klee]

Hi,

today I found three entries such as the following in our daily usenet report:

Dec 17 12:03:56 genba rnews: rejected 437 Body of header is all blanks in "Organization" header

Is there any way to find the message IDs of the corresponding messages?

BTW, the messages have been posted using rnews running from a modified
mailpost.  Of course, one could add logging of date-time to mailpost,
but maybe there's a simpler solution.
