11.9.2 SMTP Example

This example prompts the user for addresses needed in the message envelop (`To' and `From' addresses), and the message to be delivered. Note that the headers to be included with the message must be included in the message as entered; this example doesn't do any processing of the RFC 822 headers. In particular, the `To' and `From' addresses must be included in the message headers explicitly.

      import rfc822, string, sys
      import smtplib

      def prompt(prompt):
          sys.stdout.write(prompt + ": ")
          return string.strip(sys.stdin.readline())

      fromaddr = prompt("From")
      toaddrs  = string.splitfields(prompt("To"), ',')
      print "Enter message, end with ^D:"
      msg = ""
      while 1:
          line = sys.stdin.readline()
          if not line:
              break
          msg = msg + line
      print "Message length is " + `len(msg)`

      server = smtplib.SMTP('localhost')
      server.set_debuglevel(1)
      server.sendmail(fromaddr, toaddrs, msg)
      server.quit()
