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 [login to view URL] as [login to view URL] 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.

Hi. This kind of problem is because your server is listed into blacklist. There are severals ways for improve your security and, eventually, dont be blocked by blacklist server, foe example, dkim and spf records. I can help you installing it without problems. Open to qustions. P.D, I can speak spanish.
