Have you restarted Graylog after enabling the SMTP transport in the configuration file?

If you changed the settings in the correct configuration file, restarted Graylog, and the SMTP server is reachable from the machine running Graylog, email alerts should work.

Make sure you edited the correct file and restarted the correct Graylog node.
