I found the solution in the 2nd edition of the Sendmail book: create
the file /etc/service.switch and place in it the single line

hosts   /etc/hosts

The book gives details.  Good luck. 

For those who forgot what the problem was, here's the original:

I found the solution in the new edition of the Sendmail book: create
the file /etc/service.switch and place in it the single line

hosts   /etc/hosts

This solved my sendmail problem with both 2.1.5 and 2.1.6 neatly.
The book explains why this works.  Good Luck.  ...DanW

For those who wonder what the problem was, here's the original.
(It's a non-issue for people running DNS, I think.)
