Note: If you are trying to unsubscribe from the
cert-advisory mailing list (check the email header), there are different
instructions.
To change your email address, you must follow the instructions for

the following options, substituting the email address you are
unsubscribing for the example text:
unsubscribe technical-alerts example@example.com
unsubscribe alerts example@example.com

Note: You do not need to send the email from the account you are
