I have a little strange problem. I have newly configured postfix server(with dovecot). Everything is fine for almost all mail recievers, except for gmail's. I have this header 

using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)

in every single mail, but for google is still not encrypted and I see it with unlocked red padlock icon. And it is going to spam only for gmail.

Postfix v2.11.3
smtpd_tls_security_level=encrypt

Does anyone had the same problem ? Thanks !

You need to use smtp_tls_security_level. smtpd_... is for incoming email; smtp_... is for outgoing email.

You can also see http://www.postfix.org/TLS_README.html#client_tls for more details.

  • I knew that. It's so obvious that I should use smtp_tls_security_level, but why I didn't make it.. Thanks. It works! – digode Apr 14 '16 at 05:37
