flask-mail gmail: connection refused

问题:

I'm getting the following error when I attempt to use flask-mail to send an email through my gmail account.

error: [Errno 10061] No connection could be made because the target machine actively refused it

I've tried configuring flask-mail in various ways, but so far I always get this error.

Here are some sample configurations I've tried:

1. app = Flask(__name__) mail = Mail(app)  app.config.update(dict(     DEBUG = True,     MAIL_SERVER = 'smtp.gmail.com',     MAIL_PORT = 465,     MAIL_USE_TLS = False,     MAIL_USE_SSL = True,     MAIL_USERNAME = 'my_username@gmail.com',     MAIL_PASSWORD = 'my_password', )) 

2. app = Flask(__name__) mail = Mail(app)  app.config.update(dict(     DEBUG = True,     MAIL_SERVER = 'smtp.gmail.com',     MAIL_PORT = 587,     MAIL_USE_TLS = True,     MAIL_USE_SSL = False,     MAIL_USERNAME = 'my_username@gmail.com',     MAIL_PASSWORD = 'my_password', )) 

3. This configuration is from the flask mega-tutorial (http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-xi-email-support)

   app = Flask(__name__) mail = Mail(app)  app.config.update(dict(     DEBUG = True,     # email server     MAIL_SERVER = 'smtp.googlemail.com',     MAIL_PORT = 465,     MAIL_USE_TLS = False,     MAIL_USE_SSL = True,     MAIL_USERNAME = 'my_username',     MAIL_PASSWORD = 'my_password',      # administrator list     ADMINS = ['my_username@gmail.com'] )) 

Has anyone else experienced a similar problem?

As far as I can tell there is nothing wrong with this configuration. The only problem is that your application is not using it. You should update configuration before you initialize Mail:

app = Flask(__name__)  app.config.update(dict(     DEBUG = True,     MAIL_SERVER = 'smtp.gmail.com',     MAIL_PORT = 587,     MAIL_USE_TLS = True,     MAIL_USE_SSL = False,     MAIL_USERNAME = 'my_username@gmail.com',     MAIL_PASSWORD = 'my_password', ))  mail = Mail(app)

In addition to zero323's answer, adding the configuration before creating a Mail object should help, but if it gives an SMTPAuthentication error with a gmail server, then just for testing purpose one may allow less secure apps to login for a while - https://myaccount.google.com/security#signin
