Configure BoxTrapper

To adjust the settings, do the following:

2. In the Email addresses for this account box, list the addresses that forward mail to this account, separated by commas.
3. Type your name into the Your Name box.
4. In the The number of days that you wish to keep logs and messages in the queue. box, set how many days logs and queued messages are retained.
5. Set the threshold in the Minimum SpamAssassin Spam Score required to bypass BoxTrapper box.
   Note:

   A message whose spam score falls below the Minimum SpamAssassin Spam Score required to bypass BoxTrapper value goes straight to the recipient. A low threshold makes BoxTrapper challenge more senders; a high one lets more mail through untouched. A threshold of 5, for instance, triggers more challenges than 10. The default is -2.5. Learn more in the SpamAssassin spam score section below.
6. Tick or untick the checkbox for automatic whitelisting. When active, BoxTrapper whitelists every address you write to.
7. Tick Automatically whitelist the To and From lines from whitelisted senders (whitelist by association) to whitelist the addresses in the To and CC lines of incoming messages from whitelisted senders.
8. Click Save.

SpamAssassin spam score

SpamAssassin examines each message and assigns a numeric score; the higher the score, the likelier the message is spam. Negative scores are possible too and usually indicate legitimate mail. It combines many checks, such as Bayesian filtering, blocklists, DNS (Domain Name System) lookups and online databases. The SpamAssassin documentation lists the tests. A score has no upper or lower bound.
