Hello,
I've already mentioned it in another thread, but maybe it's an update-issue in stead of server issue.
My problem: It seems (well, it doesn't work anymore, so it's an issue) that the option "Require that all senders are authenticated" on 'Distribution Group' not longer works. I really don't know why this happends and when it doesn't work anymore, because it did work when creating the group (and the updates weren't available).
The situation (so maybe there's another option to find out what causes the problem):
Pineapp -> Exchange 2007 SP2 Rollup 4. The pineapp is being used before I installed updates of Exchange (and it did work with this setup), so in my opinion, this can't be the problem.
If someone could help me, or point me to a (new) direction so I can solve the problem with our Exchange server, that would be great :).
