Why are all e-mail forwarding verifications required to be logged in as administrator?

Why are all e-mail forwarding verifications required to be logged in as administrator?

I recently set up several e-mail accounts for my users and added forwarding  addresses so that they can get a notification at another e-mail address for those that wanted it.

The user's verification e-mails don't have a link to click and verify, rather they have some instructions that requires them to log in as *administrator*, locate their e-mail address, and Click "Verify Now" to enter their verification code.

Why are all users required to log in as administrator to verify their forwarding accounts? 

Thanks in advance.
