Other software vendors sell NDR management utilities that may be more flexible and easier to configure and use -- for example, MailBasketMD from TurboGeeks or MAPILab's Mail Storage Guard. Some solutions also eliminate returning the NDR back to sender, which can help reduce spam.
A manual process, which would be inefficient in larger sites, could retrieve the original email message from the BADMAIL folder. A utility release by Microsoft archives and purges the BADMAIL folder contents with a BadMailAdmin.wsf script run through Windows Task Scheduler. Scanning through the email looking for "real email" amongst potentially lots of spam could be a hassle though. The utility supports Exchange 2000 SP2 and Exchange 2003.
