Objective I want to reroute all mail from a particular domain via a different smtp gateway while leaving all other domains to go via the existing smtp gateway. Plan I have a x400 (SMTP * cost=1) and IMC (SMTP * cost=100) connector on Exchange 5.5 (existing setup), I want to add a 2nd IMC in our site which will have a address space of SMTP <domain.com> cost=1 and change the cost of X400 to 20. will this allow me to do what I intend to achive ? Thanks Kul
