[Beowulf] RFC: Restrict posting to subscribers only ?

Doesn't the subscription confirmation e-mail kind of handle this 
already? I suspect spammers send from random or fictitious addresses and 
don't check (or even receive) email sent to those addresses, so it's 
unlikely they'll be confirmed as subscribers to the mailing list.

I think Greg raises an excellent point that we shouldn't reply to 
spammers. Perhaps we should just silently ignore posts from 
non-subscribers. If they are real humans, they should figure it out 
easily enough that they need to subscribe to post. Most mailing lists 
have a web page advertising the list, with instructions on how to 
subscribe to the list and list policy, such as needing to subscribe in 
order to post. I think that should be adequate to keep spam away but not 
real humans.

Besides, don't we hate when people post something that clearly indicates 
they didn't RTFM? ;)
