The Keywords: or Subject: psuedo headers need to appear within
the first topics_bodylines_limit of a text/plain message (or
the text/plain part of a multipart/alternative message). By
default, it just looks at the first 5 lines of the body (but it
can be changed to scan all or none of the message looking for
the psuedo headers). The regular expression search is done in a
case insensitive way. When a match is detected, the message
gets an X-Topics: header showing the matching topic name.
The regular expression should not be trying to match the
Keywords: or Subject: field name... only the "content" of those
headers, or "licensing" in your example.

If you are sending text/plain messages with the psuedo header
words starting in the first column, you might want to confirm
the value of the of topics_bodylines_limit for the list. (Use
