problems canceling my own articles with rn

[Tom Christiansen]

I'm running (t)rn configured so that I share an NFS-mounted
spooling directory amongst many hosts, which means I'm using 
rn's mini-inews to submit articles as though it were rrn.
This all works just fine. 

The problem is I just can't talk it into canceling my articles.
If I attempt to so from the host I posted from, it says not
my article, because I'm not on the host it really seems posted 
from, the one with the spool directory resident.   I'm on pixel,
and the spooling machine is convex.

If I go over to the server machine, (which really only sysadmins
can do, not normal users, so it's not a good general solution)
it complains that the article was posted by "news at convex" not by
"tchrist at convex.com".    Looking at the various headers of posters,
I see that these three possibilities arise:
    convex.COM
    convex.UUCP
    convex.com
    convex.convex.com
I imagine that the UUCP line is just plain bogus.   But the other
three are the same.  So even if I get the poster right, I have the
problem with the DNS names.  Should these get run through the resolver
to come back canonicalized?  

Before I go hacking on rn, I thought I'd ask the net, since I'm sure
others have had to deal with this.  Any comments or suggestions?

thanks,
