5.4.5 Spam Filtering
Specify the number of Spam Scanner instances to be created and used
for spam analysis.
Number of spam scanner
instances Specify the number of Spam Scanner
instances to be created and used for spam
analysis. As one instance of the spam
scanner is capable of processing one mail
message at a time, this setting defines how
many messages will undergo spam analysis
simultaneously.
You might need to modify this setting if you
enable Realtime Blackhole Lists (DNSBL/
RBL) for spam filtering. For more
information, see “
Enabling Realtime
Blackhole Lists ” , 238 and “ Optimizing
F-Secure Spam Control Performance ” , 240 .
The server must be restarted after this
setting has been changed.
IMPORTANT: Spam analysis is a
processor-intensive operation and each
spam scanner instance takes approximately
25MB of memory (process fsavsd.exe). Do
not increase the number of instances unless
the product is running on a powerful
computer.
