Hello guys,
I am new to the forum and usually i try to search a lot before asking for help.
Now my problem is basically the red lock icon you see on your gmail account saying "this message was not encrypted"
I have tried numerous things and maybe some of you guys can help me out.
My sentora panel is located at cohst81n2b.domain.gr (i dont post my actual sentora panel url for obvious reasons)
My domain is thomasfoskolos.gr
I have set up my MX record to cohst81n2b.domain.gr
I have set up /etc/postfix/master.cf and /etc/postfix/main.cf
When i use checktls.com "email TO:" tool everything seems ok and i get this.
http://imgur.com/xgJN3WK
But when i try checktls.com "email FROM:" tool i get this reply message.
It seems my server does not issue the STARTTLS command.
Below are my Main.cf and Master.cf files and my OS is Centos 7
Main.cf
Master.cf
Thanks in advance,
Thomas
