Sender address rejected: not owned by user

[daedric7]

Steps to Reproduce

1. ... Deploy wger via docker-compose
2. ... Configure prod.env with email addresses
3. ... Configure prod.env with valid smtp config

Expected results: Emails sent with the account defined in FROM_EMAIL

Actual results:

wger_server  | Exception in thread Thread-3 (send_email_thread):
wger_server  | Traceback (most recent call last):

wger_server  | smtplib.SMTPRecipientsRefused: {'[email protected]': (553, b'5.7.1 <[email protected]>: Sender address rejected: not owned by user [email protected]')}

No email is sent.

docker compose exec web python3 manage.py sendtestemail [email protected]

actually works, so i believe smtp settings in prod.env are correct.

ENABLE_EMAIL=true
EMAIL_HOST=mail.mydomain.com
EMAIL_PORT=587
[email protected]
EMAIL_HOST_PASSWORD=********************
EMAIL_USE_TLS=True
EMAIL_USE_SSL=False
[email protected]

I tried adding multiple settings to prod.env, to no avail:

[email protected]
EMAIL_FROM_ADDRESS='wger Workout Manager <[email protected]>'
DEFAULT_FROM_EMAIL='wger Workout Manager <[email protected]>'

The EMAIL_FROM_ADDRESS is always the default one:

docker compose exec web python3 manage.py diffsettings | grep example
WARN[0000] The "jw" variable is not set. Defaulting to a blank string. 
ADMINS = (('Your name', '[email protected]'),)
EMAIL_FROM_ADDRESS = 'wger Workout Manager <[email protected]>'  ###
MANAGERS = (('Your name', '[email protected]'),)

It seems you run into wger-project/docker#35 (I'm closing here, feel free to comment in the other ticket)

The strange thing is, I could send emails without any problems
