HiExchange Server 2007There is an unpersonal mailbox. Mails are sent with an appplication using the email address of this mailbox as reply address.All incomming emails to this mailbox are forwarded to a distribution list. That works so far.Now the application sent an important email to an email address with a typo. An NDR was sent to the reply address. I can find this NDR in the mailbox, but it has never been forwarded to the distribution list. And because nobody looks into this mailbox (why, all mails are forwarded), they didn't realize that this important email wasn't sent.Why are all the emails forwarded except the NDRs?RegardsPeter

Thank you for replying.I know this link, but that's only about how to copy NDRs received by any mailbox to a separate mailbox. What I need is how to forward an NDR received by mailboxA to a distribution list.I guess that's not possible, isn't it?RegardsPeter
