then does always immidiately forward its mail to the sendmail on the
machines where the spool originates.

Sun introduced this because they don't trust the users in configuring
their sendmail daemons.

One gets the pre SunOS 4.1 behavior of sendmail if you comment out the
source of all failure, the remote mode. (OR macro in
