We Have been getting a lot of spam coming into our organization and adding to that somehow our Groups are also being picked up even the most obscurely named ones.
We have over 1500 groups and there is no way to do this 1 by one.
I have been searching for any sample scripts which would let me take a csv file of groups and set the "From authenticated users only" flag under the Message Restrictions Section of the Exchange General Tab.
Does anyone know what commands I could use to do this or if anyone has a script I could use?
If it's Exchange 2007, you should be able to just use PowerGUI and its Exchange 2007 pack.
1. Install it on a computer which has Exchange 2007 or Exchange 2007 management tools. 2. Go to Exchange 2007/Recipients/Distribution Groups. 3. On the Actions pane click Change Properties and select True in the RequireSenderAuthenticationEnabled parameter.
Unfortunalty we are still on exchange 2003 and won't be migrating for another few months. Is there any way to find out the code used for that? Maybe it may apply for the 2003 group.
