The IP address used by ruby-talk, ‘221.186.184.68’ is listed on [APEWS.org](http://APEWS.org) (Case C-130) as blocked and has been since 2007. An upgrade to my spam filtering prevented ruby emails appearing in my inbox recently. I repeated the email thinking it had not arrived at the list server. I have now whitelisted the IP and hopefully all will be well from now on. Thanks Matz for your response to my first email. Regards Paul F Fraser ---

You can see that it has blocked the entire netblock (212.184.0.0/13 - over 500,000 IP addresses belonging to NTT). Probably the people who run it don’t expect to communicate with anyone in Asia.
