I'm using Postfix, Roundcube 1.4.3 and devcot to receive and send emails on my vps server.
I'm able to receive emails but the errors are occurring when sending the email, the mail never reaches the destination.
Port 587 is what roundcube is using.

Error I'm getting in Roundcube ui
SMTP Error (-1): Connection to server failed.
You don't have anything listening on the port you are trying to send mail through. You need to configure your postfix to listen and accept mails on port 587.
