Well, the last time I had to deal with such mailing lists
(unsubscribing after my From: had changed from to
) I just forged the From: header. This isn't even
security by obscurity, because it's not obscure - it's obvious that you
only need to supply a properly forged From: header to bypass such silly
checks.
There are already solutions used that really solve the problem:
Sending a confirmation email or requiring a password.
