To prevent spammers
from using the
IMSVA MTA
as a relay for spam, configure relay control by adding the mail
domains on your network to the
Relay Domains list.
When
IMSVA receives
a message, it looks at the final destination of the message and
compares it to this list.
IMSVA 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
Relay domain settings are different from Domain-based delivery
settings.
