[stunnel-users] Default passthrough to different destination?

Hi All

Wondering if there’s a way to pass an unencrypted connections traffic to an alternative location if a client does not SSL/TLS with the stunnel server?

So considering stunnel running as a server to wrap an unencrypted SMTP server. If the SMTP client/server talks SSL/TLS all is good and as expected. If the client tries to talk without encryption it gets disconnect.

Is there any way to send this traffic elsewhere rather than disconnecting the client? So that stunnel is adding an SSL/TLS option to a service rather than enforcing it. Splitting the traffic to destination servers based on if the client was encrypted or not.

Thoughts?

Thanks

Mark
