The Advanced Configuration

The Advanced Configuration section allows fine tuning of the spam filtering capabilities. Generally this should be left alone and the system will work fine. The options are explained below.

Full Header Reporting

If enabled, the spam filter will append detailed information about the scanning results in the header of the email message. This information is useful for debugging those messages that the spam filter missed.

Max Message Size to Spam Scan

Scanning a message for spam takes up a lot of system resources. If the message has a very large size, too much time may be spent analyzing the message. Here you may specify the maximum size of the message that are scanned for spam. If an email is larger than this amount in kilobytes, that message is not scanned for spam. Spam typically isn't larger than 150K.

RBL Lookup Timeout

Real-time Black-hole List (RBL) are servers on the Internet that keep a database of machines and domains that regularly send spam. The spam scanner contacts RBL if that option is enabled. Here you can specify the timeout in seconds for contacting the RBL servers. If the scanner doesn't receive a reply from an RBL server after this many seconds, it drops the RBL checks.

Local Languages

The Spam Scanning will not assign a spam point value for being in a foreign language for each language selected here. More than one Local Language can be set.

Local Character Sets

As with the Local Languages above if an e-mail is sent in a character set not defined as a Local Character Set it will be assigned a spam point value.
