Answer
The remote server has attempted to deliver a message with a line length that exceeds the Internet Standard maximum length of 1000 characters. GMS will handle long lines with no problems but some on bound messaging servers and client may not be able to cope (it may cause a buffer overflow). The default action is for GMS to allow long lines but the administrator has configured GMS to make sure all email messages meet the Internet Standard for line length.
In this case, session Undefined was processing an email from the IP address Undefined from Undefined to Undefined. Because one or more lines in the message were over 1000 characters, the message was rejected with
Undefined
.
This is the correct result, no action is required by you.
