Nope. Mail can only go to the SMTP servers that I designate. As I said before, this setup is very common in an enterprise. Usually a gateway SMTP server will receive all the mail and then, based on a number of criteria, relay the mail through regional or departmental SMTP servers. The criteria that controls the relaying could be anything, really, from domain to username. > > > > On 6/26/07, Andrew Jorgensen <[EMAIL PROTECTED]> wrote: > > On 6/26/07, Michael Torrie <[EMAIL PROTECTED]> wrote: > > > On Mon, 2007-06-25 at 21:45 -0600, Mike Lovell wrote: > > > > I'm not quite sure if > > > > this is what you are looking for.
