Monitor whether or not an email is sent securely #124

Closed Redsandro closed 5 years ago

Redsandro commented 5 years ago

I can watch a secure and an insecure port and output a message to the console to see if a request was sent to either of them.

But some servers prefer to use an insecure port (secure: false) and run STARTLS to switch to secure communication. Is there a way for me to monitor when a payload is sent securely, or whether or not STARTTLS was used (successfully)?

You can get all required info from the logger
