NDR question

I am trying to determine exactly how the NDR messages are generated.  My situation...We send out emails for a customer using our Exchange server.  However, the delivery errors are dumping on both my Exchange server and their Groupwise server.  So, what I need is for the receiver of the email to be able to reply and go to the customers email server, but, all of the delivery errors only to go the my Exchange server??? Can this be done??

I think so, RFC 822 page 21,

For systems which automatically  generate  address  lists  for replies to messages, the following recommendations are made:

            o   The "Sender" field mailbox should be sent  notices  of any  problems in transport or delivery of the original messages.  If there is no  "Sender"  field,  then  the "From" field mailbox should be used.

            o   The  "Sender"  field  mailbox  should  NEVER  be  used automatically, in a recipient's reply message.

            o   If the "Reply-To" field exists, then the reply  should go to the addresses indicated in that field and not to the address(es) indicated in the "From" field.

page 3 of http://www.rfc-editor.org/rfc/rfc821.txt shows that the NDR should go to the email address of the sender, thus your client. So I do not think it can be done unless you reconfigure the groupwise server to drop these NDRs.

MAIL <SP> FROM:<reverse-path> <CRLF>

This command tells the SMTP-receiver that a new mail
transaction is starting and to reset all its state tables and buffers, including any recipients or mail data.  It gives the reverse-path which can be used to report errors.

Let me see if I understand this correctly.  The FROM address is what is used to issue errors.  So, can I set the FROM address to me@myserver.com and the REPLY address to them@theirserver.com? Would this solve my problem?  Replies would go to them and errors would go to me?
