2 issues: 1) I need to know when someone is attempting to use any domain but what we have approved for testing. This is the reason for the redirect. I'm open to alternatives but other than babysitting log files or every userid mailbox used REJECT is tough to track.
2) I only have 3 domains that are valid destinations. I don't want to write transport rules for the other 100million domains I don't want to allow. Anything a little less maintenance intense solutions?
