Max x400 received lines MTA option

Received header line MTA options:  (integer)
As the MTA processes a message, it counts the number of X400-Received: header lines in the message&#x27;s header. (X400-Received: header lines are added to messages processed by a PMDF-X400, PMDF-MB400, or other X.400-to-Internet e-mail gateway.) If the number of Received: lines exceeds the  value, the message is entered into the MTA destination channel queue area in a held state. This check blocks certain kinds of message forwarding loops. The message must be manually moved from the held state for processing to continue. The default for  is 50.
