I have long recommended unlinking subscribing from granting list posting
privileges. In my case, some of my ezmlm-idx based lists use a four day
waiting period, others (mostly small lists) only have posting privileges
granted manually.
While it is possible for a spammer to forge around subscriber address
checks, I cannot recall a single instance of this happening on my lists
in several years, and only one example of a spammer who hung around
long enough to get around the waiting period.
I have perl scripts which peruse the logs for new subscribers and
activate posting privileges, and also perl scripts that I can 'bounce'
e-mail to which activate or de-activate posting privileges for the poster.
