          send - mail routing and delivery

          upas/send [ -b ] [ -i ] [ -r ] [ -x ] [ -# ] [ mailaddr ...

          Send is not normally run directly by the user.  Instead,
          mail protocol agents like smtpd (see smtp(8)) and mail pre-
          parers like marshal(1) fork and execute send.

          Send reads a message from standard input and disposes of it
          in one of four ways:

          +o  If mailaddr refers to a local mailbox, it appends it to
             the recipient's mailbox.

          +o  If mailaddr is remote, it queues the mail for remote

          +o  If the -r option is given and the mail is undeliverable,
             the message mail rejected: is printed on standard error,
             setting exit status.

          +o  if the -r option is not given and the mail is undeliver-
             able, it appends the mail to
             /mail/box/username/dead.letter and prints a message to
             standard error.

          The file /mail/lib/rewrite determines exactly how to deliver
          or queue the mail.  The decision is based purely on the
          recipient address.

          The options are:

          -b  suppresses the addition of the To: line.
          -i  let the message input be terminated by a line containing
              only a period, for compatibility with old mailers.
          -x  do not send mail, but instead report the full mail
              address of the recipient.
          -#  do not send mail, but instead report what command would
              be used to send the mail.
          -r  input is via a pipe from another program.  Expect a From
              line at the start of the message to provide the name of
              the sender and timestamp.  This implies the -b option.

          Send uses the login name as the reply address.
