Blocked Domain Try to Send Spam

[Andrew_Pa]

Hi everyone

In Mail Settings > Blacklist , I have put an unwanted domain ("poste.it).

Now in the logs (/usr/local/psa/var/log/maillog) I see this time this information every 3 seconds.

postfix/smtpd[13489]: NOQUEUE: reject: RCPT from localhost.localdomain[127.0.0.1]: 554 5.7.1 <[email protected]>: Sender address rejected: Access denied; from=<[email protected]> to=<[email protected]> proto=SMTP helo=<User>

How can I completly stop this domain from may server?

Thank you very much for your time

You probably want to do this through the firewall. By blocking all traffic from it's respective IP address.
