DESCRIPTION
Use this field to configure what the ZyWALL does if it does not receive a valid
response from the anti-spam external database.
If the ZyWALL does not receive a response within seven seconds, it sends the
e-mail digest a second time. If the ZyWALL still does not receive a response
after another seven seconds, it takes the action that you configure here. The
ZyWALL also takes this action if it receives an invalid response.
Here are possible reasons that would cause the ZyWALL to take this action:
1. The ZyWALL was not able to connect to the anti-spam external database.
2. The ZyWALL connected to the anti-spam external database, but there was
no HTTP response within seven seconds.
3. The ZyWALL received an error code from the anti-spam external database.
4. The ZyWALL received an invalid spam score (for example a number higher
than 100).
5. The ZyWALL received an unknown response to the anti-spam query.
