Maybe in your area you can get a residential ISP whose mailrouters are
always reliable.  Where I live there is one cable modem provider with
no competition; its mailrouters usually work but do not always warn you
in good time that mail is queued.  With my own MTA I can tell right
away whether mail has been delivered or not -- except when I'm forced
to "dumbhost" my mail through my ISP's mailrouter.

This is a smarter way to do it.  Wouldn't you admit that the problem is
not from MTAs on dynamic IP addresses, but rather from infected Windows
machines on dynamic IP addresses?
