STARTTLS: Check for implicit vs opportunistic TLS #24

Closed steffenfritz closed 8 months ago

steffenfritz commented 1 year ago

Is your feature request related to a problem? Please describe. When a server does not support STARTTLS and a client does not enforce aka has "implicit TLS" it might drop to an insecure connection.

Describe the solution you'd like mxcheck should check for opportunistic vs implicit TLS. opportunistic should be yellow or red and implicit green.
