GMS has received a message for an address that could not be interpreted correctly. All email addresses should start with a user name, followed by an at sign (“@”) and a domain name. By rejecting the message at the MAIL clause, GMS is saving considerable network bandwidth because the message body has not been sent over the network.
In this case, session Undefined was accepting a message from the server at Undefined. The server provided MAIL command of
which could not be interpreted so GMS responded with an error message of Undefined. To resolve this problem, you will need to check the IP address of the system sending the message. If the IP address is one of your local machines, contact the person using the machine and ask them to correct their email address in the mail package they are using. If the IP address is outside your domain, you will need to contact the owner of the IP address and let them know that someone there has their configuration incorrect. In either case, the sender should get an error message returned telling them that their email could not be accepted.
