SMTP server configuration only working/used when running on Laptop, but not virtual host

[schihei]

The SMTP configuration only works when I run the Docker container on my laptop, but when I move the same configuration to my virtual host, the IP address 127.0.1.1 is used as SMTP server.

The error I am receiving is the following:

My configuration is:
EMAIL_SERVER_HOST=XXXX.de
EMAIL_SERVER_PORT=465
EMAIL_SERVER_USER=cal@XXXX.de
EMAIL_SERVER_PASSWORD=XXXXXXXXXXXXXX

It seems the configuration is used to verify the SSL certificate of the SMTP server but not for sending.

Thank you very much for your help.

I'm facing the same issue @schihei were you able to figure this out?
