Note the trailing colon.  There is some characteristic of messages FROM
listserv (that I can't remember the details of at the moment) that,
combined with whatever software AOL is using, cause them to send commands
to [log in to unmask] _correctly_ with an internal "To:" that has the same
address with a trailing colon.  That's what Listserv rejects.
