Spam Firewall keeps on sending unknown mails

[Randy]

Hi Janos,

I successfully bypass the internal and outgoing mails to SPAM firewall, but unfortunately after the deployment Spam firewall keeps sending unknown mails to 130.185.108.72 with the status of Deferred.

Is this normal?

Thank you.

I'm not sure how piler is involved. Please elaborate the issue.
