While I am not a lawyer, everything I have read, including far too many court documents online, says that this is not a "grey zone" at all. You own each email you compose. Copyright law therefore gives you the exclusive right to publish or choose a publisher. In the U.S., public interest may override copyright law, such as when Diebold's corporate email was published when revealing voting machine problems. It is far better to assume that no permission to publish is received with an email. Seventy years after the author dies, you're free to publish without permission, unless it was anonymous, pseudonymous or a work for hire, then it's 95 years after publication or 120 years after creation, whichever is shorter.Jon said:BTW, regarding legal lines, publicly re-printing emails is a "grey zone". Same with other assumed "private" communications, such as PMs in forums. While there's nothing I'm ashamed to see in the email I sent you, it is something to keep in mind. Spamming forums, as Richard's marketing company has done, is also "technically" illegal.
