[Mailman-Users] Goodmail spells doom for mailing lists?

[Jonathan Dill]

Has anyone talked about the changes planned by AOL, Yahoo! etc. to 
require "certification" via Goodmail or just be blocked?

What will happen to a mailing list such as this one?  Will AOL and 
Yahoo! users just be out of luck or have to get an e-mail account with 
another provider in order to receive mailing lists?
