What is a good spam detection threshold?

What spam threshold are you using? I understand that it can be a value between 0 and 1, and that the default is 0.9, but what is a resonable starting point?

Thanks

The defaults are fine for most organisations/users. Mine are set at 0.15 and 0.1 and work for me but you may want to adjust yours according to the levels of spam you are receiving.
