So you got a local database of all valid email adresses on each domain
at the MS installation? if so I want to know how you implemented this,
as you are saying that you do not control all systems ? Do you sync
the exchange user db ?
We have disabled all NDR's, cause we dont what to be a backscatter
source, so if you have a good way of implementing the above with
Exchange, i'm listening.
