question on system.net.mail.snmtp

[Carlos]

Hi all,

I am trying to upgrade an app under 1.0 to 2.0, and one of the features
is to use the .net.mail.snmtp namespace instead of web.mail.
I got an exception that says:

Command not implemented. The server response was: Command not Supported

When using my snmtp server. Now, when I used our exchange server with
internal addresses the command was successful.

Can anybody share any ideas ?

Thanks in advance,

Carlos.
