Defining the P option works just fine.  Jim's case was sending mail to
a bad user on the server machine; since the client sendmail is notified
immediately by the server that the user is unknown, the *client's*
error-disposal logic determines who gets the bounced mail.  If the
server receives mail that is then undeliverable (e.g., mail to
"@server:baduser at host"), then *its* error-disposal logic comes into
play.  So defining the P option on the server has no effect on mail
that is undeliverable at the client.
