### Run SimpleLogin Docker containers
To run the server, you need a config file. Please have a look at [config example](example.env) for an example to create one. Some parameters are optional and are commented out by default. Some have "dummy" values, fill them up if you want to enable these features (Paddle, AWS, etc).

In case your Postfix server is on another server, it's recommended to enable TLS on Postfix submission to
secure the connection between SimpleLogin email handler and Postfix.
This can be enabled by adding those lines at the end of `/etc/postfix/master.cf`
```
submission inet n - y - - smtpd
-o syslog_name=postfix/submission
-o smtpd_tls_security_level=encrypt
-o smtpd_sasl_auth_enable=yes
-o smtpd_tls_auth_only=yes
```
Make sure to set the `POSTFIX_SUBMISSION_TLS` variable to `true` in the SimpleLogin `simplelogin.env` file.
