Table 86 Anti-Spam: External DB (continued)

LABEL

DESCRIPTION

 

 

Action for No Spam

Use this field to configure what the ZyWALL does if it does not receive a valid

Score

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.
