This might be interesting to some... from another group I am on.

Hi all,
An item of general interest.
I'm told that Verisign has inserted a wildcard DNS record into the .com and .net TLDs, with the effect that a query on an unregistered domain name now resolves to a specific IP address. This hasn't manifested itself here yet, but I guess it will over the next day or so.
One of the side-effects is that any attempt to block email by checking that the sender's domain exists, will now fail. Another side-effect concerns mis-configured mail servers or DNS entries: if you are configuring a mail relay and/or put a typo in the MX record, you may get unexpected results since the IP address indicated by Verisign happens to be running an SMTP server.
I'll refrain from repeating the outraged comments on various discussion groups. It will be interesting to see how this situation evolves.
Regards,
