Yes, but...
While signing Mail From is doable for domains (like yours, I believe) that use
the same MTA for signing and receiving, there is no way to do that when the
MSA and MDA are separated and possibly not even run by the same company.
Another way to put it is that DSNs are no problem as long as everyone does
something that almost no one does and it's impossible for a lot of us to do.
