Salam, Currently we're transitioning from Exchange 2003 to Exchange 2010, usually in 2k3 when I added a new connector I could apply restrictions on that connect for a single user or a group of users (I.E by default the connector either accepts all users or reject all users and I can specify exceptions). I've been looking around with Exchange 2k10 SP1 and probably missed on how to apply such restrictions. Thank you in advance, Kindest regards.Abdullah^2

Hi, I don't think that Exchange 2010 has such a facility. You may go for the following ways: 1. Create a new Exchange servers in a different AD site for different groups, configure new send connector (Mayn't be a better solution :) ) 2. Write a custom Transport Agent with any Visual studio tools and control it as you like. Mor details here: http://msdn.microsoft.com/en-us/library/microsoft.exchange.data.transport.enveloperecipient.routingoverride.aspx 3. Use a third party gateway to achieve your goal. ExSBR is such a tool listed here: http://www.slipstick.com/exs/misc.asp . Contact the company too to check it's cmpatiability with 2010 Regards from www.windowsadmin.info

Salam, So if I want to disallow certain users from sending e-mails to outside the internal domain scope. I can't? That is frustrating indeed. Thank you, Kindest regards.Abdullah^2

Hi, Set up a transport rule that matches the conditions: from members of ditribution group sent to users outside organization send bounce message Regards from www.windowsadmin.info

Salam, Thank you ManU this is what exactly I wanted, now I have to go and create distribution groups on the AD and separate the users. Thank you very much, Kindest regards.Abdullah^2

If the intension is to just refuse to send messages FROM a group of people TO some set of domains then it's a pretty easy thing to do to reject the messages they send. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
