Oops, I wanted to reply to this, too, but forgot to quote it!
My company's MDSA servers receive about 400-500 worms a minute. It is
not practical for me to follow up on them in the way you propose. I
used to do that, but there is just too much volume now. My main
concern is keeping them away from our users, and not causing NDR
backscatter if I can help it.
