At no point did I say this email changed the canon. A user asked me to ask Jeff so I did. This is his response.

While interesting, it doesn't change what was said on the show. Nothing supernatural can cross a mountain ash barrier. As far as the canon is concerned it only appears to apply to banshee. That is all.

While knowing the writer's intent is informative. Jeff or some of the other writers could, at sometime in the future, decide to change the current situation. We will continue to gauge the canon for the site by what is shown on the actual broadcast of the show.
