ASP.NET Send E-Mail Via Exchange 2007 Relay IP

Hi

Im trying to send an e-mail via out Exchange 2007 server, but I get an error saying that it cant send. If I change the IP to an exchange 2003 server it works fine.

I know the relay is setup properly on my 2007 server as I use it for another app I wrote using access 2007.

The Code Im using is below

Thanks

Hi

After some more testing it works fine if I use basic authentication. It seems a bit buggy, but it will do as is for now.

Thanks for your help
