I've been investing some serious hours to get Postfix/Dovecot working with SNI certifiactes and the Plesk Premium Email Extension (Kolab) now.
However,
will keep returning the global server's mail certificate, not dovecot's certificate from the local_name section.
Querying the dovecot's IMAP port directly returns the correct certificate (9993):
How can I make the Plesk Premium Email Extension (Kolab)/Guam SNI compatible? This is quite urgent, because I confirmed a roadmap with this feature after upgrading to Obsidian.
Thank you in advance!

Code:
echo | openssl s_client -connect localhost:993 -servername xyz.com
