The FreeBSD mailing lists are the only ones I've come across that have the policy of "anyone can post". I was stunned to discover that you could post to the FreeBSD mailing lists without being subscribed. All other lists I've encountered have the policy of "only subscribers can post" with the obvious intent of keeping out spam. Their thinking is also "ask here" and "get an answer here". I'm curious to know what percentage of mailing lists today allow posting by non-subscribers. Although I've only been subscribed to this list for about a year I don't recall ever seeing spam that wouldn't have been stopped by requiring subscription to post. Has there ever been any spam to this list that used a forged subscriber address? - John J.
