From within a VB.Net Winforms application I am sending emails via SMTP using our local Exchange server. I am specifying a From: address belonging to an employee within my company, so to the recipient it looks like the email came from that employee. The To: addresses come from a table in our SQL database.

When I use Outlook on my desktop to send an email to an email address that does not exist, I get a bounceback email saying that my original email was undeliverable due to an invalid address. I would like the same thing to happen with emails sent from my VB application, with the bounceback going to the From: address I specified. But that does not happen. Any ideas why, and how to fix that?
