Mail::SpamAssassin::Plugin::Pyzor - perform Pyzor check of messages
Pyzor is a collaborative, networked system to detect and block spam using identifying digests of messages.
See http://pyzor.sourceforge.net/ for more information about Pyzor.
use_pyzor (0|1) (default: 1)
Whether to use Pyzor, if it is available.
pyzor_max NUMBER (default: 5)
This option sets how often a message's 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_timeout n (default: 3.5)
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).
You can configure Pyzor to have its own per-server timeout. Set this plugin's timeout with that in mind. This plugin's timeout is a maximum ceiling. If Pyzor takes longer than this to complete its communication with all servers, no results are used by SpamAssassin.
Pyzor servers do not yet synchronize their servers, so it can be beneficial to check and report to more than one. See the pyzor-users mailing list for alternate servers that are not published via 'pyzor discover'.
If you are using multiple Pyzor servers, a good rule of thumb would be to set the SpamAssassin plugin's timeout to be the same or just a bit more than the per-server Pyzor timeout (e.g., 3.5 and 2 for two Pyzor servers). If more than one of your Pyzor servers is always timing out, consider removing one of them.
Specify additional options to the pyzor(1) command. Please note that only characters in the range [0-9A-Za-z ,._/-] are allowed for security reasons.
This option tells SpamAssassin specifically where to find the "pyzor" client instead of relying on SpamAssassin to find it in the current PATH. Note that if taint mode is enabled in the Perl interpreter, you should use this, as the current PATH will have been cleared.
