My clients are seeing a lot of returned mail due to: "No unauthenticated relaying permitted" type errors being reported from the receiving server. Since we are sending to them they should accept and deliver and we are not relaying. Our logs show this as the error reply from the far side.
Normally I would think someone misconfigured their perimeter MX server, but since it seems to be affecting more than just a handful of domains I am trying to determine the problem. Is anyone else seeing alot of this lately or have an idea whats behind it?
