4.5.6. Notifications about rejected
messages
If the
Reject this message
action has been specified as the action over
messages with a specific status, filtration server will not route such messages to
their original recipients. Instead, it returns to message sender a notification
informing that mail delivery is impossible.
Filtration server uses two types of notifications. The use of messages of a certain
type is determined by the product settings and recognition results.
The first type of notifications is
Reject message
. Such message is transmitted to
the sender immediately during an SMTP session together with an error code
informing that the message has not been delivered. The example of an SMTP
session below contains a
Reject message
text:
