Yep, I didn't mean only he.net, but if you ask for these features they will point you in the right direction and provide rudimentary support. I don't suppose the majority of hosts have even heard of it these days. But for me, Procmail is the only solution that comes to mind the allows you to do pretty much anything you imagine with emails arriving on your domain.
