And if someone try to ddos/attack some host that is not really, for example
wlfkqspfqwekalsdkfsdfal.com .
They will not can send a judicial process, will?
After all, would not be sent to their just to some idiot host that they
And, its legally, they match all the hostnames?
For example, if cocacola.com, have there cokacola.com, the same sounds
equal.. they could to process verysign, no?
Any lawyer on the list?
On my point of view its not right.

ALLOW the TO and FROM fields of the SMTP negotiation to happen.

Moreover, they're still working on this SMTP server. Just one week ago,
they were running another Postfix-like MTA, with completely different

What if Verisign is planning to open more similar TCP/IP services on that
host? What if they're going to further modify the existing ones, to better
invade individuals' privacy?
