SMTP not working in production?

Question

Django

Hello! You need to fasten the sending of a message (reviews) from the site to the mail. Everything works fine through the local server, but when I upload it to the hosting (heroku), it gives an error
SMTPAuthenticationError at /massage/
Next comes the suggestion to go to the mail from the browser and try again. Does not help. Next, I'll throw the smtp setting in settings.

#Gmail
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = '************'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

Am I doing something wrong? Please help! Thank you!

Answer 1

you don’t need a new acc + preferably 2FA and an application password,
then read what Gmail asks for, maybe he has Heroku in the bath

Answer 2

Stop using Google, mail and other similar mail services for this. With a high probability, in the fight against spammers, Google may block such connections or impose any restrictions.
