Prombel with rule actions

[Gareth]

I have just upgraded and have set the following in the configuration :-

SpamAssassin Rule Actions = SpamScore>=25=>store,non-deliver

It correctly does not deliver the mail but it does not seem to be
putting it in the quaranteen directory. I would like it to quaranteen
the mail in the same way that it does a virus so that it shows up in the
quaranteen when I use mailscanner.

Have I made a mistake with the syntax or it is saving the file somewhere
else?

Thanks
Gareth
