You might want to fix /etc/hosts for this to work again. Seems to be a local
configuration problem on your machine.

There was no probelm with /etc/hosts. After extensive research at the
sendmail.org web site, the only work around for the problem I could devise was
to add
FEATURE(`accept_unqualified_senders')dnl to sendmail.mc and then recompiling.
This is not a clean solution but will do for the time being since I do not
accept external LAN mail since sendmail is not fully configured. I have upgraded
to RH Linux 9 with this same sendmail configuration. Final goal will be to
configure sendmail to accept internal LAN mail only to keep security related
data internally.
