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

When I add new mailaccount in Outlook 2019, it prompts me with a Security Alert for autodiscover.domaina.com with correct certificate smart.mydomain.com 


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

thank you
Urs
