exchange 2010 TLS and Spam Soap smarthost

Greetings,

TLS is enabled on my send connector (I believe that is by default). The send connector goes to our smart host (spam soap). I have the option to enable TLS on the smart host.

We are now required to implement TLS with a firm we work with. They use opportunistic and stated that we could do the same. When I run tests from checktls.com and mxtoolbox, I see that TLS is enabled on my end.

I guess my questions are

- Do these test results simply mean that I am able to use TLS, but it is not fully configured? Or is it fully functional so-to-speak?

-Does anyone know if I need to configure anything else, on spam soap or my 2010 server, for the emails from our server to the other firm to use TLS? I have not heard back from the other firm yet to test and spam soap sent me a link to a FAQ with no info regarding my question. I would like to be ready on my end when they are.

Thanks for any help

your tests from the internet confirm that TLS is enabled and functional.  Opportunistic is the way to go.  As long as their TLS is setup, both servers should negotiate.

thanks aindelicato. I guess I will just have to wait on them to confirm now.

I see this in a header from one message sent from them to me yesterday. Does it mean TLS was used to transmit the message? Also, is .local on my servers a problem?

Thanks again
