NAME
      smtp - send SMTP mail to a remote host using Simple Mail Transfer
      Protocol

SYNOPSIS
      smtp [ -D ] [ -d domain ] [ -H helohost ] [ -N ] sender host recip ...

DESCRIPTION
      smtp sends a message to a remote host host using the Simple Mail Transfer
      Protocol (SMTP).  The message is read from standard input.  sender is
      used to identify the sender of the message and the recips are used as the
      recipients.

      When establishing a connection, smtp will use the first transport for
      which netdirgetbyname(3) returns an address, based on hostname,
      transport [returned from getnetpath(3)], and service smtp.  Normally,
      this will be the ``tcp'' transport.

      The options to smtp and their meanings are as follows:

      -D          This option turns on debugging.  Debugging information is
                  printed on standard error.

      -H helohost This option can be used to set the hostname used in SMTP HELO
                  message (this defaults to the system's name).

      -d domain   This option can be used to set the domain name to be used for
                  this host.

      -N          This option disables the sending of MX records.  It should
                  not be used on systems that run the Domain Name Server.

      smtp is normally run by the smtpsched process to deliver mail queued in
      /var/spool/smtpq.
