No encryption over smtp


I read online that I simply need to click "Copy to postfix" in ssl management page in order to make tls working over smtp...

But... It's still not working.. the connection is secure over imap (incoming) but I can't fix outgoing.. it's still not encrypted..

Did I do something wrong? Am I missing a step?

Thank you!

Edit :

Usermin is now broken.. I can't send an email anymore..

Okay guys,

I got it working,

Encryption server to server : smtp_tls_security_level = may in postfix config file

ssl connexion on port 465 (ssl with smtp) Open port 465 in firewalld


Have a nice day
