Hello, i did a smtp server with my vestacp everything seems to be working good except sending emails to pop3 clients.
On PHPMailer i can send to @gmail.com and even to @randomdomain.com if this is running trough imap.

On PHPMailer side there's nothing that i can change, after searching for the last days someone said on a stackoverflow post that it might be some DNS problems or firewall.
On the firewall everything seems to be working aswell since i can telenet pop3 ports showing dovecot service.
Is there something that im missing?

thank you
