When I try to send an email using Flask-Mail to Gmail's SMTP server using the settings below, I get [Errno -2] Name or service not known
. How do I fix my configuration to send email with Gmail?
from flask import Flask, render_template, redirect, url_for
from flask_mail import Mail, Message
app = Flask(__name__)
app.config.update(
MAIL_SERVER='smtp@gmail.com',
MAIL_PORT=587,
MAIL_USE_SSL=True,
MAIL_USERNAME = 'ri******a@gmail.com',
MAIL_PASSWORD = 'Ma*****fe'
)
mail = Mail(app)
@app.route('/send-mail/')
def send_mail():
msg = mail.send_message(
'Send Mail tutorial!',
sender='ri******a@gmail.com',
recipients=['ri*********07@msn.com'],
body="Congratulations you've succeeded!"
)
return 'Mail sent'
- The server is "smtp.gmail.com".
- The port must match the type of security used.
- If using STARTTLS with
MAIL_USE_TLS = True
, then useMAIL_PORT = 587
. - If using SSL/TLS directly with
MAIL_USE_SSL = True
, then useMAIL_PORT = 465
. - Enable either STARTTLS or SSL/TLS, not both.
- If using STARTTLS with
- Depending on your Google account's security settings, you may need to generate and use an app password rather than the account password. This may also require enabling 2-step verification. You should probably set this up anyway.
MAIL_SERVER = 'smtp.gmail.com'
MAIL_PORT = 465
MAIL_USE_SSL = True
MAIL_USERNAME = 'username@gmail.com'
MAIL_PASSWORD = 'app password generated in step 3'
A small but important addition to davidism's answer:
You must have '2-step verification' enabled on your Google account before you're able to set up app-specific passwords.
