A little while ago there was a discussion of duplicate site names
and the answer was to use domains because then the fully qualified
site name WILL be unique.

WELL... I got some mail with a from that looked like:
"From: texsun!sun!hplabs!hp-sdd!sdcsvax!ncr-sd!onion.SanDiego.NCR.COM!bethh@tundra.UUCP"
First it is confusing because all the sites are in order except that
"tundra.UUCP" is our nearest neighbor.  Why that is at the end is a
mystery to me.  OK.  So I figure that this is just a foible of the
conventions and try to create a return path and come up with:
"To: tundra!texsun!sun!hplabs!hp-sdd!sdcsvax!ncr-sd!bethh@onion.SanDiego.NCR.COM"
Is this correct or am I all screwed up?

This mail gets bounced back to me with:
"554 texsun!sun!hplabs!hp-sdd!sdcsvax!ncr-sd!bethh@onion.SanDiego.NCR.COM... Unknown domain COM"

I also tried bethh@onion.ncr.com thinking that upper case was
causing me difficulties (well it worked on other stuff).  No
dice.  Bounced with the same message.

Can anyone tell me what the problem is?
