Prodigy's mailer is probably altering the message header before it
is sent to your list. One quick, dirty, and usually very effective
solution is to subscribe the person under the a010-1128.klmz.splitrock.net
and the prodigy address, but set one of the subscriptions to NOMAIL
so that duplicate messages do not get sent to the subscriber.
