Imagine the following: 2 mail relays and one mail-storage. The mail-storage has a webinterface on which you can redirect your mail. You redirect the mail to a mailbox which does not exist, and because of the redirect the Return-Path points to the redirected mailbox. The Server to which is redirected sends a bounce-mail. The bounce-mail comes in to the mail-relays. The mail relays do not see that the mail is rotating, because of the forwarding. Then the mail is forwarded and bounced again and gets bigger and bigger.
I might be reading this wrong, but it looks like the "redirect" sends with the local user as the sender, instead of the original sender. This is the problem. The bounce cannot get back to the real sender. A traditional forward does not change the sender address. You could mark redirected mail with a X-header, and check header and body of incoming for that X-header. But what would you do when you find it? Force local delivery? Then your user never sees it. Throw it away? Then the original sender does not get notified. So I think the solution is not to send the redirected mail with the local user as the sender address.
