The Engine Performance Settings dialog (linked to via the Performance item of the left navigation) offers
the Anti-Spam component performance settings:
Move the slider left or right to change the level of scanning performance ranging between Low-end desktop /
High-end desktop.
Low-end desktop - during the scanning process to identify spam, no rules will be used. Only training
data will be used for identification. This mode is not recommended for common use, unless the
computer hardware is really poor.
High-end desktop - this mode will consume a large amount of memory. During the scanning process
to identify spam, the following features will be used: rules and spam database cache, basic and
advanced rules, spammer IP addresses, and spammer databases.
The Enable on-line checking item is on by default. It results in more precise spam detection via
communication with the Mailshell servers, i.e. the scanned data will be compared with Mailshell databases
online.
Generally it is recommended that you keep the default settings and only change them if you have a
valid reason to do so. Any changes to this configuration should only be made by expert users!
