we want to improve our mailing lists by handling all the bounces we get. As I saw there are different approaches. One checks the badmail folder in IIS mailroot folder. Others check a email account using pop3 to get the bounces.
Our setup is an exchange server behind a IIS SMTP server. We send from different servers (out) and different addresses. But incoming is all the same server.
What software can help us to easily handle the bounces? I do not want a tool, that removes all emails from the server (pop3), as I imagine to scan employees accounts as well as automatic accounts. The tool should allow actions to be taken (call a batchfile, or call a URL to do something with the address bounced.
What about the difference between the badmail folder and the Nondelivery Emails? Do both cover all bounces or just combined?
