How to enable TLS for quarkus-mailer?

[nickhais]

Hello!

I use quarkus-mailer library to implement email sending features in the application. Basically, the application just retrieve data for email from DB and send them daily (like reminders).
As we are using our own SMTP server in our company our Security team told me to enable TLS and to be sure that while application connecting to the SMTP.
Could you please advice me how to do that?

Should I use sth like that quarkus.mailer.start-tls=REQUIRED in application.properties file?
