email containing token with high spamcount only gets an unsure

[Gerrit Thede]

Hi,

I am receiving annoying spam emails with differing content, but always with
the same last lines that go like this:


-------------------------------------------------------------------------------------
Moechtest du dich abmelden? Sende eine eMail
mit dem Titel "abmelden" an byebye987 at netscape.net"

I received and classified lots of these, but I still get an "X-Bogosity:
Unsure, tests=bogofilter, spamicity=0.500000, version=1.0.3".
Today I checked the tokens:

bogoutil -p ~/.bogofilter/wordlist.db netscape.net byebye987

spam    good    Fisher
netscape.net                   86       0             0.999901
byebye987                       86       0             0.999901

How can I get these messages to be recognised with a higher spamicity?
