This is not a good idea, as many people noted: this closes the door to
casual users who do not want to subscribe to yet another mailing list.
My experience with CLISP maintenance may prove valuable to you:
at this time, clisp mailing lists do not get _any_ spam (well, almost).
We have 3 public mailing lists (devel, list, announce).
announce is moderated, so no spam is possible.
devel is subscriber-only, so no spam is possible either.
clisp-list is open (and it is marked as the main support venue on SF).
nevertheless, it does not get much spam either!
go to your list admin interface, privacy options, and set the
"bounce_matching_headers" option to something like this:
# Lines that *start* with a '#' are comments.
to: friend@public.com
message-id: relay.comanche.denmark.eu
from: list@listme.com
from: .*@uplinkpro.com
from: .*@datasurplus.com
from: .*-daemon@
from: .*postmaster@
from: .*admin@
From: .*LISTSERV@
from: .*@sbc.com
from: .*antivirus@
from: .*Administrator
from: .*Manager
from: .*ANTIGEN_EXCH
from: .*Virus Scanner

this will redirect 99% of spam to your "admin requests" queue, which
racks up 10-20 messages per day per list for CLISP.
then get <http://www.lpthe.jussieu.fr/~zeitlin/mladmin.html>;
and clean up this queue automatically from the command line.
