Hi,
we have been doing some tests and we found an issue that we not understand.
We found a client that is sending to us emails in TLS 1.2 (we know this because the headers) but is not receiving emails when TLS is set as "Required", also we did the test Deliverability to the client and he didn't receiving none of the 32 emails... But when TLS is set as "Prefered" is receiving the 32 emails...
So the conclusion is that we can't trust only see the headers of the incoming email... Am I wrong? Then now we don't know how many clients can be affected to this change...

Hi @Lisa Mac , in March, 8 when you do the TLS change this customers are not going to receive any email, right?
I will open the case anyways.
Thanks!
