11.12.2 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 raw_input(prompt).strip()

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

    # 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:
        try:
            line = raw_input()
        except EOFError:
            break
        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()
