Using Flask-Mail to send Email through Gmail- socket.gaierr

Question

I am building a simple contact page using Flask and Flask-Mail. I built the app following this tutorial - Add a contact page - and now when I try to send the message I receive the eror `gaierror: [Errno -2] Name or service not known`. I have been googling the error for a while and can't find any similar examples on line. I can't even figure out what name or service it can't find. The traceback page will let me expand a row and execute some Python code. It provides a `dump()` function that will show me all the variables and can be called on objects to see their info if that will help. routes.py : ``` from forms import ContactForm from flask.ext.mail import Message, Mail mail = Mail() app = Flask(__name__) app.secret_key = 'development key' app.config['MAIL_SERVER'] = 'smtp.google.com' app.config['MAIL_PORT'] = 465 app.config['MAIL_USE_SSL'] = True app.config['MAIL_USERNAME'] = 'email' app.config['MAIL_PASSWORD'] = 'password' mail.init_app(app) @app.route('/contact', methods=['GET', 'PO…

Accepted Answer

I have the following settings that work for me

```
app.config['MAIL_SERVER']='smtp.gmail.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USERNAME'] = 'xx@gmail.com'
app.config['MAIL_PASSWORD'] = 'xx;'
app.config['MAIL_USE_TLS'] = False
app.config['MAIL_USE_SSL'] = True
```

Note that MAIL_USE_TLS parameter that I have. Also not sure if it matters but your MAIL_SERVER is set to smtp.google.com while mine is smtp.gmail.com.

EDIT: As confirmed, the primary issue was that your smtp host was incorrectly set. It should always be `smtp.gmail.com`
