  I discovered the hard way this morning, when I had over SEVEN HUNDRED
Cmds for various sites, that hao has been badly munging From: lines.
Although the address was "valid" in some sense, it did not conform
to the standard and several connecting sites (notably "seismo") had
a field day with addresses that looked like

site1!site2!...!user@hao

Seismo tacked on .ARPA to that (since it lacks a domain but does
not look like a regular UUCP address), resulting in a bogus address. 
It started a positive feedback loop between hplabs and seismo that
resulted in the same 5 messages bouncing back and forth via hao.
It would have been funny if it weren't such a pain in the &*#*! to
work on sendmail.cf files and such an expensive problem. My apologies
to anyone whose mail may have been lost.

   I *think* the problem is fixed now. I'm sure some friendly types
out there will let me know if it isn't! :-)
