Hi all,

I am trying to customize a few of the Exchange 2007 system message. I have
been able to change a system message so that if users send to an invalid
address at our domain, the messages replies that the address doesn't exist on
our company's mail server.

I am trying to customize the message so that if a user sends to a
non-existent domain. Currently they get this:

"A problem occurred during the delivery of this message. Microsoft Exchange
will not try to redeliver this message for you. Please try resending this
message later, or provide the following diagnostic text to your system

#554 5.4.4 SMTPSEND.DNS.NonExistentDomain; nonexistent domain ##"

I went through the DSN message on our hub server via get-systemmessage to
see the originals and try to match it up, but I can't seem to customize it.
I believe that I set 5.3.0, 5.4.4, 5.4.8. Does anybody know how to customize
this one error message? I know the syntax but I can't seem to find where
this particular message is to be found. Thanks for any help.

I am running only Exchange 2007 sp2 rollup 1 on W2K3 SP2.
