Heres my problem,
To limit the problem w/ spam i have the Delivery Restriction "receive from authenticated users only" option selected on the "staff" distribution list. However i have remote users who have there own mail server who i would like to be able to send emails to that distribution list.
So i want to allow a range of ip's to be able to send emails to that distribution list, if thats the way to go... Im using exchange 2007, hub transport, on a local site.
