The on again, off again Federal Do Not Cal List is now officially, and permanently, on again. Earlier this week a U.S. Circuit Court of Appeals ruled that the FTC and FCC's registry does not violate the telephone solicitors First Amendment rights.

If you've ever just sat down to dinner and gotten a call asking you to switch long distance services, you might think a Do Not Call List is enough to make you happy.

But, the true value of this ruling is that it opens the door to the possibility of a Do Not E-Mail List. In fact, in the new Anti-Spam laws allow for the FTC to establish such a registry. They will present such a plan to Congress sometime in May, but might also enact something without the approval of Congress (as they initially did with the DNC registry).
