Murkowski anti-spam bill could be a problem for ISPs

The definition of "real email address" is a vague thing indeed... For
example, I have many "real email addresses". I have many more addresses
I could legitimately claim are real addresses that are, in fact, routed
to /dev/null. Why heck, the use of the <> construct could be considered
a real email address. I realize the bill addresses this to a certain
extent, but not enough.

The other problem is that any spammer outside the US can fry any ISP inside
the US with this law.
