I'd definitely approve of the choice, having something like:
() Disallow posts on your wall
() Allow users to post on your wall
() Opt for emails when you receive a wall post
I personally wouldn't want emails for my wall posts (mom might see 'em and get ticked about something), so having three options would pretty much make everyone happy. The people who like wall posts with an email could have wall posts with an email, the people who like wall posts but don't want emails could have wall posts without emails, and the people who don't want wall posts at all could make it so no one could post on their wall. Obviously the 'disallow posts on your wall' and 'allow users to post on your wall' options already exist, but the third could definitely help users who want emails. And then I wouldn't have to worry about the email thing being re-implemented and having to have emails when I receive wall posts which would lead me to disable wall posts.
