Our NDR's are being forwarded to the Administrators mailbox, but are never received by the sender. I don't understand why these aren't being sent back to the sender.
Is there an exchange 5.5 setting to block non-delivery reports or is it my dns configuration with my ISP possible? How should my dns entries for my mail system be configured with my ISP??
Thanks
