Because of the relative ease in people be able to set their email address,
I am worried about someone setting their email to one of the owners of
my listserv mailing list, and then sending commands to listserv to modify
the list.  I would like to be able to protect it more.  Is there a way to do
this?  If not, is there a way to at least make it not possible to get the
header of the list so as to see what the owner addresses are?  Thanks.
