NAME

6       Mail::SpamAssassin::Message::Metadata - extract metadata from a message
7

DESCRIPTION

9       This class is tasked with extracting "metadata" from messages for use
10       as Bayes tokens, fodder for eval tests, or other rules.  Metadata is
11       supplemental data inferred from the message, like the examples below.
12
13       It is held in two forms:
14
15       1. as name-value pairs of strings, presented in mail header format.
16       For
17         example, "X-Languages" => "en".  This is the general form for simple
18         metadata that's useful as Bayes tokens, can be added to marked-up
19         messages using "add_header", etc., such as the trusted-relay
20       inference
21         and language detection.
22
23       2. as more complex data structures on the $msg->{metadata} object.
24       This
25         is the form used for metadata like the HTML parse data, which is
26       stored
27         there for access by eval rule code.   Because it's not simple
28       strings,
29         it's not added as a Bayes token by default (Bayes needs simple
30       strings).
