How to assign separate SSL certificates for different domains on a local mail server in Plesk?
This functionality is not yet implemented in Plesk.
However, this functionality is planned to be implemented in Plesk Onyx for Linux once SNI support will be available in Postfix itself (presumably in Postfix 3.4).
SNI for Mail (for Windows and Mail Enable) is already available in the Plesk Onyx 17.9 Preview 9.
It will be supported in the future stable release of Plesk as well.
