11.9.2 SMTP Example

This example prompts the user for addresses needed in the message envelope (`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 smtplib
      import string

      def prompt(prompt):
          return string.strip(raw_input(prompt))

      fromaddr = prompt("From: ")
      toaddrs  = string.split(prompt("To: "))
      print "Enter message, end with ^D:"

      # Add the From: and To: headers at the start!
      msg = ("From: %s\r\nTo: %s\r\n\r\n"
             % (fromaddr, string.join(toaddrs, ", ")))
      while 1:
          line = raw_input()
          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()
