PGP is also a fairly processor-heavy operation. It's fine when only two machines are inviolved, at either end, but as soon as a server in between becomes involved, handling lots of messages at once, it could tie itself in knots, couldn't it?

Or has someone already made that point? (blushes and sidles out)

 Does anyone here see how the authentication requirement can work without being too intrusive on the users?

From the suggestions posted so far, IP address checking just won't be reliable enough, so that leaves you with either PGP (most people don't use this, and good luck in trying to convince them to just so they can join a mailing list) or passwords/unique codes in the message body (most people will forget to add these after their first posting). Are there any other workable alternatives?
