System.Net.Mail smtp client not catching errors

Asked by metsey in Simple Mail Transfer Protocol (SMTP), Microsoft Visual C#.Net, .NET Framework 2.0

Tags: C#

I have written a windows service that reads a queue and sends emails with attachments via the system.net.mail object. I am authenticating to our exchange server to handle this. The problem is that when i try to catch errors (such as having a bad email address on the .send method) it is not catching the exceptions in my catch statement. However, an undeliverable message will come back to the From address. So i know the mail server is recording the errors.

I have been researching this but to no avail. Any advice would be greatly appreciated. I have attached a code snippet.

Regards
Mark
