Your reply is well thought-out and logical, and most certainly all admins
shouldn't be responsible for making sure typo'd URLs don't get intercepted
by their webservers.
The point I think Mr. Smith is trying to make is that Verisign seems to
*want* to intercept this private information and use it to their own
commercial advantage. Respectable sysadmins do not wish to receive form
data intended for other sites.
But really, all webmasters *should* be responsible in making sure the forms
on their site do POST to the correct URL.
Now from what I understand (DISCLAIMER: I am *NOT* a lawyer nor am I
educated in law) Verisign's Sitefinder does not violate the ECPA by merely
accepting the form data since the data was misdirected anyway. However,
it's what Verisign *does* with that data that may violate the ECPA. If
they're moving that data to Omniture (or any other org/corp), then it could

By this logic, all webservers which unintentionally accept traffic
without somehow verifying that a typo did not take place violate the
ECPA. Thats ridiculous. Do you really want a precedent where, if someone
accidentally POSTs bank information to your site instead of the URL
they meant to type, you are somehow liable? If I accidentally call you
instead of my friend and tell you all sorts of juicy gossip, is it
really your fault?
I'm bothered by the VeriSign thing, too. But you've been posting a lot
of stuff about how it breaks certain services, breaks certain mail
clients, and may be illegal. What it does to mail clients and services
is annoying, though easily fixed. But you should hardly wish for it to
be deemed illegal. That's not the sort of precedent I want to worry about.
Ta for now.
