Use pyzor -
Whether to use Pyzor, if it is available.
Pyzor fork -
Instead of running Pyzor synchronously, fork separate process for it and read the results in later (similar to async DNS lookups). Increases throughput. Experimental.
Pyzor count min -
This option sets how often a messages body checksum must have been reported to the Pyzor server before SpamAssassin will consider the Pyzor check as matched.
Pyzor whitelist min -
This option sets how often a messages body checksum must have been whitelisted to the Pyzor server for SpamAssassin to consider ignoring the result. Final decision is made by pyzor_whitelist_factor.
Pyzor whitelist factor -
Ignore Pyzor result if REPORTCOUNT x NUMBER >= pyzor_whitelist_min. For default setting this means: 50 reports requires 10 whitelistings.
Pyzor timeout -
How many seconds you wait for Pyzor to complete, before scanning continues without the Pyzor results. A numeric value is optionally suffixed by a time unit (s, m, h, d, w, indicating seconds (default), minutes, hours, days, weeks).
Pyzor max -
This option sets how often a messages body checksum must have been reported to the Pyzor server before SpamAssassin will consider the Pyzor check as matched. As most clients should not be auto-reporting these checksums, you should set this to a relatively low value, e.g. 5.
Pyzor options -
Specify additional options to the pyzor command. Please note that only characters in the range [0-9A-Za-z ,._/-] are allowed for security reasons.
Default: --homedir /etc/mail/spamassassin/.pyzor
