But perhaps there are solutions other than restricting non-subscribers. I can think of these few without much thought: 1) add grey listing (http://en.wikipedia.org/wiki/Greylisting). 2) add a header indicating whether the sender is subscribed to the mailing list. Then anyone who wants to remain on the list can add a filter to auto-delete mail when the sender isn't on the list. I don't know the numbers, but I'd bet the valid non-subscriber mail is rare. 3) Add a spamhaus IP blacklist. While I doubt this would block any legitimate mail, it is possible. So I expect this to be met with the same resistance as only allowing subscribers. Anyway, that's all I'm going to say on this subject. -Patrick
