Zitat von Michael Peter <roundcube...@alaadin.org>:
Hello, smtpd_tls_security_level = encrypt smtp_tls_security_level = encrypt I configured postfix to use encryption for incoming and outgoing emails. but incase the receipt has untrusted certificate or self signed certificate, postfix still deliver the email. How to enforce postfix not to send the email incase the receipt certificate is untrusted or self signed? Many thanks Michael Peter
You will need "verify" level for this : http://www.postfix.org/TLS_README.html#client_tls_verify
