SM7454 - Autodiscover seems using wrong name lookup for certificate
Problem reported by Urs - 6/2/2020 at 7:31 AM
I have setup a central mailserver as with a let's encrypt ssl certificate.
I created maildomains i.e., etc. all set their hostname to
Also created SRV autodiscover to

When I add new mailaccount in Outlook 2019, it prompts me with a Security Alert for with correct certificate 

What is the solution ?
I just wanna have one central mailserver for all domains and not creating a separate ssl for each

thank you
