CHAPTER 8 329
Administering F-Secure Spam Control
When the heuristic spam analysis is enabled, all
messages that the threat detection engine does
not classify as spam are further analyzed for
spam.
When the heuristic spam analysis is disabled,
only the threat detection engine scans inbound
mails for spam.
Heuristic spam analysis slows down the
performance but improves the spam detection
rate.
Spam filtering level Specify the spam filtering level. Decreasing the
level allows less spam to pass, but more regular
mails may be falsely identified as spam.
Increasing the level allows more spam to pass,
but a smaller number of regular e-mail messages
are falsely identified as spam.
For example, if the spam filtering level is set to 3,
more spam is filtered, but also more regular
mails may be falsely identified as spam. If the
spam filtering level is set to 7, more spam may
pass undetected, but a smaller number of
regular mails will be falsely identified as spam.
The allowed values are from 1 to 9.

Message Specify the action to take with a message
considered spam.
Pass through - The product allows the message
to pass through.
