I have a Flask app that is being run with Tornado:

...some imports

from tornado.wsgi import WSGIContainer
from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop

...some code

http_server = HTTPServer(WSGIContainer(app))
http_server.listen(5000)
IOLoop.instance().start()

In order to view the app, I go to 

http://127.0.0.1:5000

However, I want to be able to send email with the same app:

  print "Launch server"
  s = smtplib.SMTP(host='127.0.0.1', port='5000')
  print "Send mail"
  s.sendmail(me, [you], msg.as_string())
  s.quit()

When the time comes to send the email, the app just hangs instead of sending the mail. If I do this:

s = smtplib.SMTP('localhost')

I get an error message. Can someone help me out?

Thanks.

UPDATE:

When I use:

s = smtplib.SMTP('localhost')

I get this error message:

ERROR:tornado.application:Uncaught exception, closing connection.

Maybe tornado and smtp are not playing nice?

  • What is the error message? – Ben Darnell Apr 19 '14 at 15:17

    Are you sure you're running an smtp server locally (and on the correct port)? The error message indicates that there is no smtp server running on localhost (or that it's been firewalled off). The earlier code suggests that you're trying to use port 5000 for both smtp and http, which won't work (although it's not clear how the different code fragments in this message are meant to fit together) – Ben Darnell Apr 19 '14 at 18:33
  • I ended up just using Gmail to send the email: http://stackoverflow.com/questions/10147455/trying-to-send-email-gmail-as-mail-provider-using-python – Christopher Spears Apr 21 '14 at 02:24
