Analysis In Hybrid mode, Xeams forwards messages to another server. When configuring local domains, you need to specify the IP address of the actual server where messages should be forwarded.
This Forward-to IP Address goes into a local DNS file. Xeams does not contact a DNS server for MX lookup if the domain/IP is found in this local DNS file.
When a forward-to IP is missing or is specified as the machine where Xeams is running, messages will loop back to Xeams creating a loop.
Steps to prevent this situation Ensure the forward-to IP address is correctly specified in local domain configuration
