SMTP Configuration using SSL - Frepple

[djole988]

Hi FrePPLe community,

I’m running FrePPLe using the official Docker image and configuring it via docker-compose.yml.
I need to set up SMTP email sending using SSL (port 465) not TLS (which would be port 587).
I see that the environment variable FREPPLE_EMAIL_USE_TLS is supported in djangosettings.py, but there is no equivalent for SSL, e.g., FREPPLE_EMAIL_USE_SSL is not present in the code.

Questions:

How should I pass email SSL settings (host, port, user, password, and SSL/TLS choice) from my docker-compose.yml to the FrePPLe container?

Does FrePPLe (or its djangosettings.py) automatically switch to SSL if FREPPLE_EMAIL_USE_TLS is set to 'false' and port 465 is specified?

Or is there another environment variable or method required for SSL (not TLS)?

If I want to use port 465 with SSL (not TLS), do I need to modify djangosettings.py or is there a recommended way to mount or override settings for this scenario?

What is the exact expected behavior for FrePPLe/Django when only EMAIL_USE_TLS is provided and set to 'false'? Should I expect SSL to be used automatically, or does this default to plaintext?

Here’s an example from my docker-compose.yml:

environment:
FREPPLE_EMAIL_USE_TLS: 'false'
FREPPLE_EMAIL_HOST: mail.company.com
FREPPLE_EMAIL_PORT: '465'
FREPPLE_EMAIL_HOST_USER: myuser@domain.com
FREPPLE_EMAIL_HOST_PASSWORD: mypass

I have confirmed that using native Python and smtplib.SMTP_SSL works with my credentials and port 465, but the FrePPLe container fails with authentication or connection errors.

What is the correct and supported method for this setup? Do I need to patch the Django/FrePPLe settings or is there an officially recommended approach?

Thank you in advance.
