Comment 4 for bug 471770

I have confirmed that AdminMergeBaseView.doMerge() intentionally resets the duplicate accounts email addresses to NEW to prevent identify theft. So what should be done in the case where the email address is used for a mailing list? Sending out emails to request confirmation of the email address would be a better experience. but that does not prevent this oops from happening. I see two options to fix this.

A) Set all subscriptions to the current preferred email address.
B) unsubscribe the user and send en email explaining how to resubscribe.
