No, it's running on localhost, no need to check router.

What's the output if you telnet to port 7777 like this:

$ telnet localhost 7777

Re: "Errore SMTP (451): Fallito l'inserimento del destinatario"

So the iredapd service is not running. Please try to start it, and check the log in /var/log/iredapd/iredapd.log.

If it cannot be started, please turn on debug mode and try again:

Re: "Errore SMTP (451): Fallito l'inserimento del destinatario"

I'm confused here. You mentioned that it's MySQL backend, but the iRedAPD shows it's using OpenLDAP backend. Could you please try this:

# cd /opt/iredapd/
# find . -name '*pyc' | xargs rm -f {}
# service iredapd restart
# service postfix restart

Then try to send email again.
