Answer
GMS was operating the smart redirect rules and a rule matched that requested that the message should be redirected to another account.
The smart rules are processed in order until one of the rules are matched. Once a rule is matched it is immediately actioned and all processing of the smart rules are stopped for that message.
In this case, session Undefined was using the rule which matched the parameters
- Undefined = Source server/client IP address;
- Undefined = MAIL clause (the protocol FROM details);
- Undefined = Local IP address that the message was delivered to (this may be different for multi-homed systems); and
- Undefined = RCPT clause (the protocol TO details).
- The message was redirected to Undefined.
- How do I block a single email address ?
- What Is Mail Meta Language (MML)?
- How do alerts work?
- What is SMTP Response Code Theory?
This is the correct result, no action is required by you.
