RHN sends me email intended for other users

Description of problem:
Periodically I get email from RHN about other people's accounts. Most recently was a warning to the "dentj" user that their inactive server will be deleted soon. This seems to happen whenever someone creates an account with email address firstname.lastname@example.org; the Red Hat mailserver helpfully rewrites this to email@example.com, and then firstname.lastname@example.org, so the mail comes to me.
I see two fixes for this; ideal would be both.
1) Check email addresses at account creation time to make sure they actually work, perhaps by sending verification email.
2) Don't add .redhat.com to email addresses coming out of RHN in order to make them sensible; just let them bounce.

This sounds bad. We should totally look at this.
If you're going to close this as WONTFIX, please at least make some sort of
comment about why. It seems like it should be very easy to fix this in the
mailserver configuration, just make it treat mail coming from RHN without the
usual special rules.
I got four more of these emails on 5/17.
This happens only to people with @redhat.com email addresses, whose email-name matches to the email-name of a customer address that fails.
Somewhere in the networking stack, *long* after an email has left RHN, lies a filter that notices failing emails. Wherever that filter is, it takes a failing email of the form "firstname.lastname@example.org" and tries delivery to "email@example.com".
We've tried to find out where this happens, but it's very far away from RHN, in the production cloud somewhere.
I'm going to close this - RHN isn't causing the behavior, and we can't fix it :(
