Spam settings

Dear All,

I facing a spam problem that is caused by a wrong setting I guess.

Many users are receiving e-mails like this:

mail body:
qiz http://lqvz59f.krovatka.su?anoc tog xaf
d b pevu surune

subject: gej

X-Spam-Status: No, score=-1.899 tagged_above=-999 required=4.31 tests=[BAYES_00=-1.9, RCVD_IN_DNSWL_NONE=-0.0001, URIBL_DBL_REDIR=0.001] autolearn=ham

and it has a score of -1.899

I thought that an email with a body like this it should get a higher score?

What am I missing?

Thank you
Tamás
