All three machines have the same FQDN.
something like A.mydomain.com, B.mydomain.com, C.mydomain.com
The IP numbers are X.Y.Z.170, .171 and .172
All three machines have MX records. they all have the same domain name.
It is a big deal to request changes from the provider so I was hoping
there was a way
to just tell the two new machines that incoming email to them just send
on over to the the
Is there a way to do that - or am I going about this the wrong way?
