Gotcha - it wasn't actually clear from the way you wrote it originally.

So in that case it is really jurisdictional. The US falls down pretty heavily on the corporate-owns-everything, but not everywhere does.

In my experience It's pretty common for companies to retain emails of people who have had outside contacts at least for a while, so nothing gets dropped on the floor, usually redirected to a supervisor or whomever took over the projects.
