I am able to send/receive email from my domain accounts but when I am checking my domain statistic at: https://www.checktls.com/TestReceiver
Then I got an error:
Cert VALIDATION ERROR(S): self signed certificate
So email is encrypted but the recipient domain is not verified
Cert Hostname DOES NOT VERIFY (mydomainname.com != www.example.com)
So email is encrypted but the host is not verified
How can I fix it?
