      You're blocking MAPS' test, but you leave your server open to

'Just about anywhere else' is a gross exaggeration. We currently block over
3000 entries, from class B's to individual ips. As an example, all of
uu.net dial-ins, but NOT their SMTP servers. As another example, BellSouth
is the ILEC here, so many of our customers hold a dsl account from them
as well as a dial-up or domain with us. We can't block their ips. Some
of these customers keep their accounts because of the email address they 
had with NetSide for years. And no, reselling dsl from BellSouth is not
a viable economical option.
      MAPS isn't "forcing" you to do anything, you know.  You're very
      welcome to continue to leave it open.  And, likewise, everyone
      else is equally welcome to block all mail from your server, with
      or without MAPS' easy removal process.

Do you speak as a MAPS official, JD? Thought you held the title of MAPS
Product Manager. The forcing part comes with the conditions you attach.
They may hear your call and tighten the blockade. Then again, some may
start thinking independently...

It is not the integrity of our server, it's the deviant line from your
prescriptions that hurts here. Perhaps it's time an ISP questions your 
authority to make the rules. Risking our neck, just like that. While I
respect your convictions and even ideals, I am strongly questioning your
methods by which you implement them. You are still treating our company
like some rogue .cn domain. One shoe fits all.
