To prevent spammers from using the
IMSS MTA as a relay for spam,
configure relay control by adding the mail domains on your network to the
Incoming Message Settings list. When
IMSS receives a message, it
looks at the final destination of the message and compares it to this list.
IMSS discards the message under
the following circumstances:
-
The destination domain is not in this list
-
The parent domain of the destination domain is not in this
list
-
The host is not on the Permitted Senders of Relayed
Mail list
Incoming message settings are different from message delivery domain settings.
For more information see
About Message Delivery.
