Strange bogolexer result

[Boris 'pi' Piwinger]

Hi!

I was wondering how much the use of spam markers set by some
mail server next to mine is correct. So I wanted to look up
whe values in the database. So taking a typical header:

[3.14 at pi ~]$ echo "X-Spam-Flags:
<.POSTMASTER-RFC-IGNORANT.PIGS.PIGS-UNKNOWN. at mx2.univie.ac.at>[195.34.187.2:detebe.org]<lycos.com>"
|bogolexer
normal mode.
get_token: 1 'x-spam-flags`
get_token: 1 'mx2.univie.ac.at`
get_token: 5 '195.34.187.2`
get_token: 1 'detebe.org`
get_token: 1 'lycos.com`
5 tokens read.

That says, that the information is not looked at, it looks
like an e-mail address, but why?
