qmail-remote - send mail via SMTP

          qmail-remote host sender recip [ recip ... ]

          qmail-remote reads a mail message from its input and sends
          the message to one or more recipients at a remote host.

          The remote host is qmail-remote's first argument, host.
          qmail-remote sends the message to host, or to a mail
          exchanger for host listed in the Domain Name System, via the
          Simple Mail Transfer Protocol (SMTP).  host can be either a
          fully-qualified domain name:


          or an IP address enclosed in brackets:


          The envelope recipient addresses are listed as recip
          arguments to qmail-remote.  The envelope sender address is
          listed as sender.

          Note that qmail-remote does not take options and does not
          follow the getopt standard.

          End-of-file in SMTP is encoded as dot CR LF.  A dot at the
          beginning of a line is encoded as dot dot.  It is impossible
          in SMTP to send a message that does not end with a newline.
          qmail-remote converts the UNIX newline convention into the
          SMTP newline convention by inserting CR before each LF.

          It is a violation of the SMTP protocol to send a message
          that contains long lines or non-ASCII characters.  However,
          qmail-remote will happily send such messages.  It is the
          user's responsibility to avoid generating illegal messages.

          qmail-remote prints some number of recipient reports,
          followed by a message report. Each report is terminated by a
          0 byte.  Each report begins with a single letter:

          r    Recipient report: acceptance.

          h    Recipient report: permanent rejection.

          s    Recipient report: temporary rejection.

          K    Message report: success.  host has taken responsibility
               for delivering the message to each acceptable

          Z    Message report: temporary failure.

          D    Message report: permanent failure.

          After this letter comes a human-readable description of what

          The recipient reports will always be printed in the same
          order as qmail-remote's recip arguments.  Note that in
          failure cases there may be fewer recipient reports than
          recip arguments.

          qmail-remote always exits zero.

               Current host name, for use solely in saying hello to
               the remote SMTP server.  Default:  me, if that is
               supplied; otherwise qmail-remote refuses to run.

               Artificial SMTP routes.  Each route has the form
               domain:relay, without any extra spaces.  If domain
               matches host, qmail-remote will connect to relay, as if
               host had relay as its only MX.  (It will also avoid
               doing any CNAME lookups on recip.)  host may include a
               colon and a port number to use instead of the normal
               SMTP port, 25:


               relay may be empty; this tells qmail-remote to look up
               MX records as usual.  smtproutes may include wildcards:


               Here any address ending with (but not
               itself) is routed by its MX records; any other address
               is artificially routed to

               The qmail system does not protect you if you create an
               artificial mail loop between machines.  However, you
               are always safe using smtproutes if you do not accept
               mail from the network.

               Number of seconds qmail-remote will wait for the remote
               SMTP server to accept a connection.  Default: 60.  The
               kernel normally imposes a 75-second upper limit.

               Number of seconds qmail-remote will wait for each
               response from the remote SMTP server.  Default: 1200.
