|Might as well be equivalent to subscribing as anonymous. The only way to

Another options exists in order to reduce the effect of spoofed email
subscriptions (where CONFIRM has not been enabled):
* DEFAULT-OPTIONS= NOMAIL
with appropriate prose in the WELCOME file (as to how to turn ON
distributions -- this then becomes both a CONFIRMATION mechanism and a
LISTSERV driver's license).
From time-to-time, you could issue the LISTSERV(R) command:
Q listname WITH NOMAIL FOR *@*
and see who is currently not receiving your list distributions (assuming
they are NOT using the WWW int'f).
