If you can still send mail from your old address, the change command can be used.
- Send mail to firstname.lastname@example.org.
- In the body of the mail type the command below, substituting your new address for "newaddr" and the actual list name for "listname."
CHANGE listname newaddr
Note: If you are subscribed to more than one list, you can type * instead of a particular list name.
This form of the CHANGE command can be used by any subscriber and results in a cookie being sent to the new address. This cookie MUST be confirmed by the new address, exactly as it was entered, or the command will fail. Note that this assumes that the user still has login access to both addresses, or at least the ability to send mail from the old address.
