SMTP AUTH does not preclude TLS or SSL
Operating system version
Windows Server 2012 Standard
Description of the issue
I noticed I cannot select SSL or TLS settings under Email Notifications unless I also enable SMTP Authentication.
TLS or SSL should be possible regardless of whether you are authenticating via SMTP.
TLS and SSL are unavilable unless SMTP Authentication is set.
The only solution at the moment seems to be to continue using unencrypted SMTP conversations until TLS or SSL can be enabled even without SMTP Authentication also enabled.
