Hello to all, How would I be able to create a Distr. List on Exchange 5.5 SP4, Win2k sp3, that solves the following scenario. I want to be able to create an external DL which will contain a list of external recipients, but I want to restrict who can send email from it. Also, the external recipients should not be able to see who are the other people that the email goes to. Thanks for your help. This is quite an emergency for me so I would appreciate your input as soon as possible. Juan
