Hi all,
A Exchange 2010 (migration from Exchange 2007) distribution group named "All" is not working as it should.
The issue is: although the dist group have restrictions at "Mail Flow Settings" / "Message Delivery Restrictions" /"Accept messages from" / "Only senders in the following list" and only a few users are allowed to send to "All", the thing is thateverybody can send messages to that list, restrictions is not working.
The check box "Require that all senders are authenticated" is not checked, but I already made tests checking it, and it seems not to change anything at all.
I have the same problem for some others lists, the funny thing is that the restrictions works ok for some lists and not for some others although it have the same configurations.
As a note, "All" is a "Non-universal group", I tried to converse it to Universal and I receive a error 5003 from domain controller. I don't know if this have something to do with the issue.
Any help will be greatly appreciated.
Thanks in advance!
