This contains some small fixes/additions to the new mail setup.
Added
- SSL email configuration
- Choose between START TLS / TLS / SSL / LMTP for smtp connection
Fixed
- Mail not working in envs where username env is missing (e.g. docker)
- This is a problem in the mail lib used, but circumvented in the Dockerfile
- Mail error showing a 500 error in the client
- Email setup reset when the config changes to make sure new email values are used
