Actually, A better way to prevent spamming would be to approve new
members before allowing them to post. I manage several listservs and
new members must give a reason why they want to join. This helps to
keep spammers, fakers and trouble makers out. For example, for this
group, you might ask new members to give a Grafton address as part of
the subscription procedure.
This is much easier and less time consuming them resorting to
approving all messages.
