rmail(1)                                                 rmail(1)



NAME
     rmail - handles remote mail received via UUCP

SYNOPSIS
     rmail [-Ddomain-name] [-T] login-name ...

ARGUMENTS
     login-name
          Specifies the login name of the user to whom the mail
          message is to be delivered.

     -T   Enables debugging.

     -Ddomain-name
          Sets the domain name.  The default domain name is
          .UUCP.

DESCRIPTION
     rmail is invoked by uuxqt to process mail messages received
     by the UUCP system. The rmail command collapses lines that
     begin with From, as generated by mailers, such as mail and
     mailx, into a single line of the form return-path!sender,
     and then passes the processed message to sendmail.  The
     rmail command is designed explicitly for use with UUCP and
     sendmail and fails if it cannot find a line that begins with
     From in the mail message.

NOTES
     Mail received from a remote computer should have at least
     one line that begins with From.  For example, if a mail
     message originates from venus!root and is sent to
     saturn!john via a computer named jupiter, the final mail
     message will look like this:

        From jupiter!uucp [optional information]
        From venus!root [optional information]
        ... text of message ...

     As the mail message passes from computer to computer,
     another From line is added at the top until the message
     reaches its destination.  Each computer may append optional
     information to the From line that it adds.  The rmail
     command uses the From lines to construct a UUCP path to the
     user who sent the mail message. In the above example, the
     path would be

        jupiter!venus!root

     When rmail calls sendmail to deliver a message, it does so
     with these arguments:

     -oee Causes sendmail to mail back error messages and to exit
          with 0.

     -oi  Causes sendmail to ignore periods (.) in the mail
          message.

     -oMssystem-name.domain-name
          Sets the $s macro in the line that begins with From.
          For the example given above, the value of
          system-name.domain-name would be jupiter.UUCP

     -oMrdomain-name
          Sets the $r macro in the domain string. For the example
          given above, the value of domain-name would be UUCP.

     -freturn-path!sender
          Specifies the return path of the user who sent the
          mail. For the example given above, the value of
          return-path would be jupiter!venus and the value of
          sender would be root.

     login-name
          Specifies the user to whom the mail is to be delivered.
          For the example given above, the value of login-name
          would be john.

       In addition, rmail invokes sendmail with the -odq option
       (queue the mail) if the load average is over 3.0.
       Otherwise, rmail invokes sendmail with the -odi option
       (deliver the mail immediately).  The rmail command runs
       setgid on the group sys so it can read the /dev/kmem file
       to determine the load average.
