I'm in the process of writing a NNTP daemon for the Cyrus IMAP project and I am 
testing with various clients as I proceed.  I found that Mozilla (as far back 
as Netscape 4.7) fails to display article info when the _optional_ XOVER 
command is not implemented.  Mozilla correctly tries to use the HEAD command 
when XOVER is not implemented, but it errors out internally and never displays 
the article summary.

I am quite certain that my server implementation of HEAD is correct, as it 
works with other clients.  FYI, as soon as I implemented XOVER, Mozilla worked 
perfectly.

A debug trace of Mozilla and a protocol dump are attached.

sorry for the spam.  making bugzilla reflect reality as I'm not working on these bugs.  filter on FOOBARCHEESE to remove these in bulk.

So it IS a Thunderbird bug! Geez... I'm on the same issue as Ken Murchison, I wasted all day trying to figure out what was wrong with my NNTP server (which I started writing *last night* :P)
My patch for bug 16913 will fix this problem, as I discovered that news.mozilla.org dislikes the XHDR command, and needed to implement it anyways.
Was about time. Thunderbird is currently unusable because it can't understand one of the main NNTP commands; unless the server implements the optional XOVER feature. Most do, but that's not the point.
Now that patch to bug 16913 was checked in, and since comment 3 said the patch would fix this bug too, should this be closed?
No one's offered any failures of this bug since bug 16913 was checked in, so I'm marking RESOLVED FIXED...
