I need a solution
People,
My client is reporting that they can send any email to my domain but not receiving any reply back or even NDR / rejection report.
When the client let say CompanyX 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
CompanyX 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 *@CompanyX.net as a good sender/whitelisted in the appliance.
Your help and advice is appreciated.
Thank you
