But I think the email options are encoded in the options database column?
Could you please explain to what setting I would need to set this so that inactive users no longer receive an notifications from my forum (except admin emails)?

You should probably require a valid email address on registration (email confirmation) so you don't get to the point of having so many bad email addresses to begin with.
