Ok thanks. <br />
Apparently I did configure DSNs correctly. Which still leaves me wondering why we are not receiving &quot;no such user&quot; DSNs. Any ideas ?

update : <br />

i've been able to find traces of non-delivery reports with &quot;no such user&quot; on our Edge server (using message tracking). For some reason it has a column SourceContext with value &quot;failure&quot; on every NDR with &quot;no such user&quot;. I can't find a trace of these messages on the Hub transport server. Something is going wrong with these messages on the Edge server.

Hi,<br />
<br />
I'd like to know a common way to configure &quot;transport settings&quot; properties in Exchange 2007. More specifically I would like to hear how to configure the option &quot;enter the DSN codes. DSN messages that have these DSN codes will be forwarded to the Microsoft Exchange Recipient&quot; on the tab &quot;message delivery&quot;.<br />
For some reason we are not receiving DSN messages when we mail something to users in other companies that don't exist. I think it might be cause the above setting is configured badly.<br />
<br />
Right now I have only the following codes in that setting :<br />
<br />
5.1.1<br />
5.1.4<br />
5.2.0<br />
etc.<br />
<br />
Or is there a way to enter all possible DSN codes ?
