one mailing list I read did the following: subscribed members are
allowed to post, anyone who has sent a message there in the past is
also allowed to post there, and any posting from someone new is
rejected, along with a message informing the sender about the list
policy and asking him to resend the mail (within a reasonable time
interval) - and he is added to the list of previous posters, so his
following mails will be acepted.
Given the fact that spammers seldom use the same mail address, it works
quite effectively.
Perhaps something like this could be adopted for debian mailing lists.
