How to generate bounce-back email notification, with some extra info included

I am just now beginning to research this, and so far haven't come up with much. So, I'm hoping you guys can help me, or point me in some sort of direction.

I am in a situation in which I need to somehow be able to detect a failed email delivery and/or bounced-back email. Then, I need to be able to sent out a notification email describing this failure, as well as include some other, specific information in the notification email as well.

At the moment, I really have no idea how to do this. The email system we have now involves some C#.NET managed code, which send the email via an SMTP Exchange server. So, my initia开发者_StackOverflow社区l thoughts are that I might be able to use email header information to accomplish this, but I'm not terribly family with all of the available email headers. I am also not at all opposed to finding and using some sort of third-party solution, but again, I'm not familiar with any such solutions or solution providers, and so I am very open to suggestions there too.

Are you using the SMTPClient class? If so, there's a SmtpFailedRecipientsException that would help you accomplish what you need.

Examples and further information given here:

Not sure if you want to download messages from an IMAP server or a POP3 server. If it's the case, you may want to check out the Ultimate Bounce Inspector component. It also let you process EML files.

You can use PostMark which allows you to programmatically process bounced emails.
