Thanks, that was pretty painless.  And thanks for the url to the
documentation section.

I've now progressed on to where I was aiming for.

I wanted to have one debian box as main mail client.  Yet be able to
send mail from a couple of others.

I've managed to get that working by aiming the secondary hosts at the
main mail host as smarthost.  That main host is inturn aimed at an
internet smarthost.

So far all working except one glitch.

Here is the cast of characters:
HOST1 Main mail host
HOST2 secondary host
User1 HOST1
User2 HOST1
user HOST2

I can send a mail from HOST2 to a user on HOST1 using the correct
address.  user1@HOST1

That main host has only two users.  I can send mail from HOST2 to
only one of those users.  That is. if, from HOST2, I send mail
to a HOST1 user like:

  user1@HOST1   It arrives in user1 slot at /var/spool/mail/user1 on
HOST1. 

However If I try sending to user2@HOST1 it never gets there. Even
though the smtp output on sending HOST2 appears to be saying it was
sent and received successfully.

   ------- ------- ---=--- ------- -------

orignating on HOST2 

tmail user2@HOST1
sending like this:
mailx -v -s "TEST 160914_163910" user1@HOST1 < ~/txtmsg.txt
LOG: MAIN
  <= user@HOST2.local.lan U=user1 P=local S=422

smtp output:
