I need a solution
We have a third party who is using the website www.checktls.com to verify that emails sent to our domain covermycab.com use TLS, I have setup an encryption partnership in the messagelabs portal but the website check is still failing. The primary MX record is using TLS but the secondary MX record isn't, is there anyway to correct this?
Thanks
