843.0. "Restrict mailing addresses?" by CHEFS::HEWITTC (Comms=tin cans+wet string) Tue Jan 28 1997 15:17

    
    This seems a relatively simple question that I'm having trouble getting
    an answer to!!  Customer wishes to know if there is anyway that
    Exchange can restrict the destinations to which selected users can 
    send mail, for example there is a mapping table somewhere that has valid
    destinations and the users that can mail to them? 
    Basically they are paranoid that some rogue user will start mailing
    company info across the Internet to competitors.

843.1	You can through connectors.	FLASK2::SYSTEM	Nigel Bridport @REO	`Tue Jan 28 1997 16:47`	8
	If you are asking the question, Can you restrict mail going out through a connector (IMC/X.400), then the answer is yes. The delivery restirctions tab of the relevant connector will enable you to restrict who sends out and who you can receive mail from. Nigel.
843.2	don't get a false sense of security	PARZVL::ccsr8.ogo.dec.com::kennedy	nuncam non paratus	`Tue Jan 28 1997 17:36`	9
	Just make sure they don't regard this as any sort of guarantee! Unless you restrict people from sending externally at all, I'm sure it's possible to get around limits on sending to a particular domain (e.g. send to a mailing list, route thru another external domain...). The company should also define an acceptable use policy and make sure employees must adhere to it. Legal restrictions are harder to circumvent than technical ones.
843.3	Reject by Host	wendys::dhcp-3-220.alf.dec.com::alfss2::jones_b		`Thu Jan 30 1997 22:35`	3
	You may also accept or reject by host in the Connections tab of the IMC. However, for this you would have to know the IP address of the competitor's mail gateway that was suspect.
