Exchange 2007 DSN Messages come from wierd address after SP1 RU7

I recently got the following question:

Hello Nathan,

I read your helpful article regarding the customizing of DSN and Quota messages in Exchange 2007. I am wondering if it is possible to modify the email address which these messages are sent from as currently the displayed address on our system is: MicrosoftExchange329e71ec88ae4615bbc36ab6ce41109e@loomisgroup.com?

Any help would be greatly appreciated.

Well I would love to say I figured this out, but I can?t!

Take a look here:

I believe this covers it!

Cheers

Nathan
