Core Antispam Engine Filter
NOTE: This filter is available if NoSpamProxy Protection is licensed.
This filter is valid for the following senders: External. The default SCL value for a single multiplier is 4.
This filter creates a fingerprint of the email to be checked based on defined criteria and compares it with the already known fingerprints. If the fingerprint is known, NoSpamProxy awards 4 SCL points. NoSpamProxy will thus already reject the email with the default settings. The filter itself has no further setting options. The administrator can only exert further influence on the filter result by weighting with multipliers.
