CONFIGURING LOOP DETECTION
This page allows you to configure the different rules for handling message loops in Internet Exchange.
To configure, do the following:
This field specifies the maximum number of received lines (that show the FQDN of the MTA machine) allowed for an incoming message. A received header line containing the MTA's FQDN is added to the message header every time a message passes through the Internet Exchange MTA. Only lines having the MTA's FQDN are counted. If this number is reached, the message will be bounced to either the sender or postmaster. This prevents mail looping.
When checked, looping messages will be bounced to the local postmaster instead of the remote sender.
