The format for defining a rule is as follows:
uri_detail SYMBOLIC_TEST_NAME key1 =~ /value1/ key2 !~ /value2/ ...
Supported keys are:
raw is the raw URI prior to any cleaning
type is the tag(s) which referenced the raw_uri. parsed is a
faked type which specifies that the raw_uri was parsed from the
cleaned is a list including the raw URI and various cleaned
versions of the raw URI (http://spamassassin.apache%2Eorg/,
text is the anchor text(s) (text between <a> and </a>) that
linked to the raw URI.
domain is the domain(s) found in the cleaned URIs.
Example rule for matching a URI where the raw URI matches %2Ebar,
the domain bar.com is found, and the type is a (an anchor tag).
uri_detail TEST1 raw =~ /%2Ebar/ domain =~ /^bar\.com$/ type =~ /^a$/
Example rule to look for suspicious https links:
uri_detail FAKE_HTTPS text =~ /\bhttps:/ cleaned !~ /\bhttps:/
Regular expressions should be delimited by slashes.
