Hello, like assumed it was my mistake. yes, on the submission port I do have "-o smtpd_tls_security_level=encrypt" and if I set "-o smtpd_tls_mandatory_protocols=!SSLv2,!SSLv3,!TLSv1,!TLSv1.1,!TLSv1.2" I really could connect *only* using TLS1.3. -> everything works like documented :-) Thanks Viktor!
