smtp, is it possible?

Hello, studying the firezone manual, I unfortunately did not find any mention of setting up sending messages to the mail, in this regard, there is a question, can this service be configured or not yet?

Yep! See the OUTBOUND_EMAIL_* env vars in the docs:

I’ve used this successfully

OUTBOUND_EMAIL_FROM=firezone@example.com
OUTBOUND_EMAIL_PROVIDER=smtp
OUTBOUND_EMAIL_CONFIGS={"smtp":{"relay":"mail.example.com","port": 1025}}
