Postfix & Dovecot, MySQL setup, but SMTP not working.

Hi everyone.. I have very limited experience of linux.. and I am trying to follow the linode guide to setup my own email server.

The guide I am using is https://library.linode.com/email/postfi … 0.19-mysql">https://library.linode.com/email/postfix/postfix2.9.6-dovecot2.0.19-mysql

Anyway after I got everything setup, I setup the account on my outlook… It will login to check for email, but when it comes to SMTP it gives error.

I don't think that receiving email is actually working either (but no bound back when I try to send email to the account from hotmail), however I have no way to check the email without finish setting up a full account on outlook so I guess lets figure out why smtp not working.

One more thing, is the guide said to use SSL for SMTP, but I think there is an error, it should be TLS? Since it is in the config file, also SSL give error about not supporting the encryption type.

However with TLS, what I got is Cannot connect to SMT for both port 25 or 587. And on 465 port it say connection interrupted.

I have check with netstat -ltpn and this is what I got

It does seems those port are open and binded. I also check firewall and they are open.. so I am lost right now.. If anyone could help, I be very thankful..

Here is my Iptable
