As I hold such catches rather than bin them, I get by with a slew of less  
fancy regexps against any header. They all pretty much like  -   

with checks for test, spam, virus, scam, help, ...

Some are worth being slightly fancy on, eg - ^subject:.*\btest.* - so  
latest gets through :-)

Don't forget - ^subject:.*The results of your email commands -
and the final triplet so messages with no subject get caught, see Mark's
