I need to do a report on emails that are returned, or because the address is spelled incorrectly, by DNS error, etc. that log is reflected (IIS or Exchange). With that code? Exchange 2003

Any idea? thanks.

Exchange doesn't store that information. You can turn up SMTP logging, but the amount of noise it will generate will drown out logs of things that you will be interested in on the server, so isn't recommended. Simon. Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
