Roaring Penguin SpamAssassin Rules
From Roaring Penguin
The Roaring Penguin SpamAssassin rules are defined in the file /etc/mail/spamassassin/69_rp_dynamic.cf, so you can search for the rule name, e.g.
$ grep "RP_D_00031" /etc/mail/spamassassin/69_rp_dynamic.cf
body RP_D_00031 /[g-y][0-9a-f]{20,64}[g-y]/i
describe RP_D_00031 Words mixed with long strings of hex digits
score RP_D_00031 4
The "body" line is the actual Perl Rule, the "describe" line is a human-readable description, and the default score shown can be over-ridden under RUles->Score Overrides.
