Actually, most email Apache email lists are moderated, and emails fromnon-subscribed users do not go through to the list unless the moderator approves it. There is just too much spam around to allow non- subscribedposts. I'm surprised to hear that jspwiki lists do not have moderation configured.
Yes, they are, but as a moderator I personally don't remember all the correct email addresses of all the people who have subscribed to the mailing lists. I doubt anyone does.
