be rated with a rather moderate value. However when multiple lists indicate potential
SPAM, it will have considerable impact on the SPAM score. The reliability of the lists
depends on how the entries have been collected. Choose which level of quality will
be considered.

collected automatically by SPAM traps.

Enable Razor2 distributed spam filter network
This feature will calculate a fuzzy checksum of some parts of an email and send it
to Razor2 servers in the Internet (TCP port 2703). Razor2 provides a database with
the checksums of known SPAM. In case of a match, the SPAM score of the mail is
increased. The amount depends on the reputation of those, who reported the SPAM
mail to the Razor2 system.
Enable Bayes filter
If enabled, the SPAM filter autonomically learns additional characteristics of unsolicited
mail (SPAM) and requested mail (HAM) while processing inbound emails. Only mails

At least 200 SPAM mails and 200 HAM mails have to be learned
before the Bayes filter is taken into account.
