Use pyzor -
Whether to use Pyzor, if it is available.
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
