LISTSERV expects a 2-word "name" in the Subscribe command as in

 SUBSCRIBE testlist Joe Jones

Some subscribers mail program includes their name in their email address

(e.g.  Ben Parker <[log in to unmask]> )

If so, and if the name is not included with the SUBSCRIBE command, LISTSERV
will look at the From: address and find it there.

Some mail programs (e.g. Aol.com) specifically do not include a name, so
LISTSERV is forced to ask for the name.

To change this behavior (i.e. to make LISTSERV not care about the name),
set the List Header thusly:

* Default-Options= Conceal

This will make LISTSERV 'forget' about names altogether.
