The mail sending works fine without the docker container. I think I actually opened the SMTP Port. Here is my docker-compose file:
version: "3.9"
services:
db:
<some postgres setup>
api:
build: .
command: python manage.py runserver 0.0.0.0:8000 --settings=api.settings.production
volumes:
- .:/code
ports:
- "8000:8000"
- "587:587"
- "25:25"
expose:
- 587
- 25
env_file:
- ./.env.dev
depends_on:
- db
entrypoint: /entrypoint.sh
mail:
build: .
command: python manage.py qcluster --settings=api.settings.production
depends_on:
- api
It doesn't work to send mails no matter if I send it as an async task with django q or directly with django.core.mail.send_mail
Here is my mail settings.py:
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'mail'
EMAIL_HOST_PASSWORD = 'password'
EMAIL_USE_TLS = True
EMAIL_USE_SSL = False
I get an OSError OSError: [Errno 99] Cannot assign requested address
The problem was that the port was blocked by my wifi.
