We have set compressed/archived files to disallow for inbound email, is there a way to allow specific senders to send these files? Does this policy overide the safe senders list?
Yeah, the policy (or domain) level Sender Allow list within the inbound policy will exempt the sender from spam, content, and attachment filtering. That should allow them to send compressed archives that are otherwise disallowed from other senders.
Let me know if you have any other questions!
