554 5.7.1 You are not allowed to connect

Hi All,

My customer is reporting that they cannot send any email to my domain but not receiving any NDR or rejection report.

When Ultimate-events try to email us it goes through without any bounce back on their end. When I check our Messaging gateway (Symantec Brightmail) and scan for the past week, but I cannot see our gateway being hit with their emails

Ultimate-events IT provided the below trace and the interesting part is this connection error “554 5.7.1 You are not allowed to connect.”

I have added *@ultimate-events.com.au as a good sender/whitelisted in the appliance.

Your help and advice is appreciated.

Thank you
