I use a regex matcher, and then if there is an attachment I block it.

I haven't tried it for this latest worm, but for other systems, someone had
suggsted:

/^Subject:[ ]*((Current|La(te)?st|New(est)?)
?)(Critical|(Internet|Microsoft|Net(work)?)( Critical|Security)?)
(Pack|Patch|Up(date|grade)) *$/o

I believe that our equivalent would be something like:

Subject:^.*((Current|La(te)?st|New(est)?)
?)(Critical|(Internet|Microsoft|Net(work)?)( Critical|Security)?)
(Pack|Patch|Up(date|grade)).*$

But I haven't tried it.
