Spammers have started using several of my email addresses so I'm constantly getting failure messages from the Mail Delivery System. Is there anyway to delete them so that I don't get them in my Inbox? I'm guessing that since they are system messages there's not but wanted to check. I've tried a user level filter but it's not working. I just implemented a domain filter but don't want legitimate failures removed if it will even remove them. Any advise would be appreciated.
