Filter on Message-ID not working

Is this just me?

As most of the spam on the newsgroups I look at comes from google groups
I’ve had a filter set up since KDE 3 days for

Groups: .*
Message-ID contains substring: googlegroups.com
Adjust score: -10

but this doesn’t seem to be actioned in 4.2

Filtering on From works Ok but I’d end up having to set up hundreds of
entries.
