Our NDR's are being forwarded to the Administrators mailbox, but are never recieved by the sender. I have checked our MailSweeper in case it is removing them but it definitly is not. I have a very thorough understanding of the mailsweeper rules and have them fully documented so am confident there are not being removed here.
Is there an exchange 5.5 setting to block non delivery reports?
