We have a DL for our entire organization with limits on who can send to that DL. We recently found out that the restrictions that we had setup do not work.
Because of the issues around testing with that DL we setup another DL for testing. At first the restrictions worked, but we had only put a few people into the authorized senders list. As we added users we got to a point where the restrictions failed. Sorry, I do not have the specifics on when it started failing. Is there a limit on how many people can be in the authorized senders list? Any ideas how to fix? Setup: Exchange 2007 Version 8.3 (Build 83.6). 2 Mailbox servers clustered with CCR, 2 hub transport / CAS servers.
