There is this person who is currently sending messages to all mailing lists. He is failing now because he is not a subscriber but he will be able to join my lists and then post his messages since most of my lists are SEND= PRIVATE (some are moderated). How do I disable this address (and others like him) from even subscribing into my lists. I dont want him in any of my lists. I have tried the command: >quiet set * serve for [log in to unmask] Invalid subscription option - "SERVE". No action taken. jacky listowner @segate.sunet.se & @ias.unu.edu http://www.unu.edu/~foo
