One more point, if checking with tls-check the domains: Caloro.ch0 fine, calm-ness.ch are still error Remaining. Configure also the local DNS Server with me two domains, but always finish with this. tlsCheck-Calm-ness.ch -> Cert Hostname DOES NOT VERIFY (nmail.calm-ness.ch != nmail.caloro.ch | DNS:nmail.caloro.ch) tlsCheck-Calm-ness.ch -> So email is encrypted but the host is not verified Thanks for any help Regards Mauri -----Ursprüngliche Nachricht----- Von: owner-postfix-us...@postfix.org <owner-postfix-us...@postfix.org> Im Auftrag von Viktor Dukhovni Gesendet: Samstag, 18.

Correct. For multiple MTA personalities there's SNI (generally not a good practice, we have MX records for serving multiple domains on a single SMTP server). This requires lookup tables that map various names to non-default certificate chains. -- Viktor.
