I use a simple VB.NET script with an Access database to send a mailshot to a few thousand subscribers from time to time. But whenever I send a mailshot, I get a couple of hundred bounce backs.

I'm looking for an easy way to remove all the mailbox unavailable, user does not exist, etc. addresses from my database.

What's the easiest way to do this? Is there some kind of .NET VBA or something which I can use within Outlook 2003?
