Yes, that's right for the Outlook plugin. The underlying engine has dozens
of options, though, and *can* be configured to do lots of other things. For
example, if the basic_header_tokenize option is enabled, a uniform kind of
tokenization of *all* header lines is performed. The basic_header_skip
option is then active too, and can be set to a sequence of regular
expressions matching header lines that *shouldn't* get tokenized.
An example of another header gimmick we ignore by default is Habeas headers:
The options search_for_habeas_headers and reduce_habeas_headers can be
enabled to pick those apart.
If the Yahoo gimmick appears to have any value, another option will surely
grow so people can try mining those; if it turns out to have a lot of value,
spambayes will then enable it by default. That all depends on someone
caring enough about it to volunteer the work, of course.
