We have a client that is going to be sending his emails via TLS encryption and he is asking some information from us. He sent us a form to fill in and I have 3 fields to complete and I have no idea what they mean.
I need this information:
- TLS certificate DN
- TLS certificate issuer CA
We work on Google Apps for Business and we use Postini for encrypting our emails (a client in the past asked for it).
I talked to the reseller who sold us and configured our emails through Postini but he is an idiot, so that is why I´m asking here if anyone knows where to get this information from
