hello, Initial position: We have 'n' exchange-maildomains hosted on a single exchange server 2007 sp1. On the other side we have one mailgateway with 'n' instances. each exchange maildomain has its own mailgateway instance and must be headed over a sendconnector. Problem: We'd like to set certain (AD)rightgroups from different maildomains to the sendconnectors. With exchange 2003 could this be achieved with 'delivery restrictions'. the 'delivery restrictions' -features on a sendconnector on exchange 2007 doesn't exist anymore. so, how can i resolve my problem? thanks alot michael
