engine's internal LiveFeed cache. The option is specified in seconds. For those LiveFeed responses whose TTL value

is less than specified minimum TTL, the antispam engine's internal cache will use specified TTL instead of the TTL

value of the LiveFeed response.

Proxy server authentication type: - Specifies what type of a HTTP proxy authentication should be used.

3.3.2.1.10 Performance

Maximum size of the used thread stack: - Sets the maximum thread stack size to use. If the thread stack size is

set to 64KB, then this variable should be set to 100 or less. If the thread stack size is set to greater than 1MB, then

this variable should be set to 10000 or less. If this variable is set below 200, accuracy can be reduced by a couple of

percentages.

Required throughput (in messages per second): - This option allows you to specify the desired throughput in

messages per second. The antispam engine will attempt to reach that level by optimizing the rules that are run. It is

possible that accuracy may be reduced. A value of 0 disables the option.

Join incremental files into one - The antispam engine, by default, will merge multiple incr files and a full file into a

single updated full file. This is done to reduce file clutter in the configuration directory.

Download only incremental files - The antispam engine, by default, will attempt to download the most size

efficient combination of full and incr file. The antispam engine can be forced to only download incr file by setting

this option to yes.

Maximum size of incremental files: - In order to reduce cpu usage while rule files are updated, the on-disk cache

files (sc*.tmp) are no longer regenerated on every single rule update. Instead they are regenerated when there is a

newer sc*.bin.full file or when the sum of the sc*.bin.incr grows beyond the number of bytes specified in maximum

size of incremental files.

Temporary files location: - This parameter controls where the antispam engine will create temporary files.

3.3.2.1.11 Regional settings

List of home languages: - This option permits you to set languages which are preferred in your email messages.

The country codes are two character ISO-639 language codes.

List of home countries: - This option allows specifying a list of countries which are considered "home" countries.

Messages routed through a country which is not on this list will be scored more aggressively. If this option is empty

then no penalty will occur.

List of blocked countries: - Allows blocking by country. If an IP address in a received header matches a listed

country the email will be considered as SPAM. The country codes aren't applied to sender addresses. Note that it is

possible for a message to have traveled through various countries before reaching the final destination. Also, this

option is only 98% accurate so blocking countries can result in false positives.

List of blocked charsets: - Allows blocking by character-set. Default SPAM score value is set to 100, but you can

adjust it for each blocked char-set separately. Note that language to char-set mapping is not 100% accurate so

blocking char-sets can result in false positives.

3.3.2.1.11.1 List of home languages

Set languages which you consider as home languages and in which you prefer to receive messages. To add a home

language, select it from the Language codes: column and press Add button. This will move the language to the

"Home" languages column. To remove the language from "Home" languages column, select its code and press

Remove button.

Block non-home languages: - This option controls whether or not languages, which are not listed in the "Home"

column, will be blocked. There are three options:

Yes

Automatically
