Please try to understand I am using email as a proof of concept for a NXTplugin. I have stated repeatedly that it is not intended for actual usage, but rather to work out the issues of having NXTplugins.
I am not even quite sure what a NXTplugin *is* but if it does has anything to do with the Nxt VM and its "scripts" then an email plugin would only be a "proof of what NOT to do".
