     SMTP(2)                                                   SMTP(2)

     NAME
          smtp - Simple Mail Transfer Protocol

     SYNOPSIS
          include "smtp.m";
          smtp := load Smtp Smtp->PATH;

          open:     fn(server: string): (int, string);
          sendmail: fn(fromwho: string,
                       towhom: list of string,
                       cc: list of string,
                       msg: list of string): (int, string);
          close:    fn(): (int, string);

     DESCRIPTION
          Smtp provides an interface to the mail transport protocol
          SMTP.

          Open opens a connection to the given SMTP server. If server
          is nil, open uses the default mail server $MAILSERVER if set
          up in /services/cs/db; see db(6). It returns -1 and an error
          message if the connection fails.

          Sendmail sends mail to the SMTP server for subsequent deliv-
          ery.  The first argument names the sender, the list towhom
          names the recipients, cc is a list of CC's, and msg has the
          text of the message. The latter may simply be a list of one
          item containing the whole message, a list of lines of the
          message or any intermediate format. It returns -1 and an
          error message on failure.

          Close closes the connection to the SMTP server.

     BUGS
          Too much copying of strings is done, especially with large
          messages.
