IronPort is an open relay.

    Hello,

My Ironport C160 acts as an open relay and due to this there are spammers who send mail from my IP , the config file is attached if anyone can help me in thi regard.

Hi Stanley,

the problem is your RAT:

          .ikea.com.kw

          ikea.com.kw

          ACCEPT

          ALL

          ACCEPT

The ALL should be set to REJECT.  Access the GUI and go to Mail Policies - RAT and change the "All Other Recipients" to Reject. This will shut down the open relay.

Best regards,

Enrico
