What is alert 8269?
GMS is in the process of delivering an email to a remote address. To do this, it needs to resolve the Mail Exchange (MX) records so that it knows the IP address of the mail server to deliver the message to. Either the MX resolution failed or returned a FQDN which needs further resolution. In this case, the additional resolution has failed.
In this case session Undefined attempted to resolve the hostname "Undefined". A resolver error code of Undefined was returned.
