> Is there any precedent you're basing this opinion on? There's no clear precedent. Clearly a judge isn't going to let us host a PDF of Harry Potter or whatever. If it ever came down to it I think there would just be a multi-pronged test, along the lines of the current test for fair use and securities law. In the case of Harry Potter it's an exogenous work that was created and copyrighted outside of an email client, it has significant economic value on its own, and there would be substantial economic harm done from us hosting it. In the case of normal email conversations most of those factors wouldn't apply, especially since in many cases seeing how people interact with one another is more valuable that the content of any individual message. Regardless, I paid my $6 to the library of congress to become a registered DMCA agent, so the copyright issue really doesn't apply unless we A) start ignoring DMCA takedown requests B) actively induce people to violate copyright.
