Mail settings for Docker deployment

[zyberwoof]

I was able to successfully deploy keybr in my home lab as a Docker container. However, I'm having trouble sending emails for the "Sign-in with e-mail" part. I'm curious if there are some SMTP configuration settings that I'm missing somewhere.

I can see in the .env.example 4 values to populate: MAIL_DOMAIN, MAIL_KEY, MAIL_FROM_ADDRESS, and MAIL_FROM_NAME. What I don't see are any variables I'd expect for connecting to an SMTP server. Things like the server address, port, username, password, etc.

I have email for my domain hosted at privateemail.com. In addition, I have another container elsewhere in my home lab configured as an open SMTP relay for my environment that I could utilize. But I'm not sure where or how I'd configure the SMTP settings for keybr to use either option.

Is keybr meant to use email the way I am thinking, or am I missing something?
