Tunning Mail server postfix on EC2 Instance

I have an email server Postfix and Dovecot installed on a EC2 instance in AWS.

I can send emails when connected to the webmail, but cant send mail through any PC or mobile phone email client.

This is the error I get on the log:

addr x.x.x.x(my client ip address) listed by domain [url removed, login to view] as [url removed, login to view]

May 22 00:07:44 mail postfix/postscreen[4296]: DNSBL rank 3 for [x.x.x.x]:53706

I need some who help me solve this issue and set up secure but functional policies.
