Hi
Mail appliance version 4.1.1.0.
I got a call from a customer yesterday to say our mails were no longer coming in with TLS enabled. I checked the appliance and it's turned on. Now this customers domain was not listed. I thought maybe someone removed it by accident so added it back in with Attempt Encryption but it still did not work. I sent a test mail to checkTLS and it failed - it was delivered but not using TLS. I sent a mail to my GMAIL account and it delivered but warned me the mail was unencrypted. I found a mail I'd sent myself a few months ago and it was encrypted. TLS is enabled on our Exchange also. Adding in gmail and checktls domains under Policy - Encryption - TLS made no difference.
I've turned TLS off, saved, Turned back on Saved but it made no difference.
When I run the tests on checkTLS.com it tells me its should be available

[000.308] TLS is an option on this server
[000.309] --> STARTTLS

[000.410] STARTTLS command works on this server
[000.641] SSLVersion in use: TLSv1.2
