One machine is not going to have enough CPU or reliability for this job.
It makes sense to do it on the mail hubs because you want to scan all
mail for viruses (incoming and outgoing) and all mail goes through the
hubs. No point in duplicating functionality.

That's not possible if the mail hubs are forwarding other domains' mail
to other mail servers run by other people, so the hubs can't know which
local-parts are valid. However call-forward recipient checking comes to
the rescue.
