Send E-mail from eml file in Python

if len(sys.argv) <= 2:
    print('Usage:')
    print('  $ python ' + sys.argv[0] + ' mailfrom rcptto <emlfile>')
    print('')
    print('Parameter:')
    print('  mailfrom: MAIL FROM address.')
    print('  rcptto:   RCPT TO address.')
    print('  emlfile:  Message file in eml format. When emlfile is not specified, an empty message will be sent.')
    print('')
    print('Example:')
    print('  $ python ' + sys.argv[0] + ' [email protected] [email protected] mail.eml')
    sys.exit(0)

server = 'localhost'
port = 25
mailfrom = sys.argv[1]
rcptto = sys.argv[2].split(',')

message = ''
if len(sys.argv) >= 4:
    filename = sys.argv[3]
    if not os.path.isfile(filename):
        print('File "' + filename + '" not found.')
        sys.exit(0)
    f = None
    try:
        f = open(filename)
        message = f.read()
    finally:
        if f != None:
            f.close()

smtp = None
try:
    try:
        smtp = smtplib.SMTP(server, port)
        smtp.sendmail(mailfrom, rcptto, message)
    except Exception as e:
        print('Failed to send mail.')
        print(str(e))
    else:
        print('Succeeded to send mail.')
finally:
    if smtp != None:
        smtp.close()

i think:
mailfrom = sys.argv[1]
rcptto = sys.argv[2].split(',')

Fixed. Thx!
