The return address "cbosgd!cbosgd.ATT.UUCP!chris" satisfies two needs:

1) It incorporates the sender's full domain-style address
(chris@cbsogd.ATT.UUCP).  So what?

	a: you may need it to reply reply from another host, where
	"x!y!z!cbosgd!chris" doesn't work and "chris@cbosgd.ATT.UUCP"
	does (if you buy domains).

	b: cbosgd, the last UUCP hop, will need it if the mail orginated
	off of UUCP.  Think of "seismo!ucbcad.BERKELEY.ARPA!bob".

2) It insulates "chris@cbosgd.ATT.UUCP" from hostile hosts by disguising
it as "cbosgd.ATT.UUCP!chris".  Only hosts that can handle these
addresses generate them, so other hosts needn't worry about them.

cbosgd!cbosgd.ATT.UUCP!chris is ugly, not stupid or wrong.  If anyone has
pretty ideas, I'd like to hear them.  Thank You.
