Shouldn't it work oppositely? Prevent the post from appearing until you explicitly approve it from a link in an email.

Sort of defeats the purpose of Posterous though. It's nice to be able to send an email and be done with it. Though for an account coming under constant attack, it'd be nice to have the option though.

Edit: What they should really do is obfuscate the posting email addresses a little. Make my posting email [e-mail], and give me the option to change it to something else if I am coming under attack.

I don't think it defeats the purpose, so to speak, since it's verified by another email. You never have to leave your email client.

It's certainly and extra step that takes away from the smooth flowing process already set in place, though.

Yes, and unless I'm missing something I don't see a way to turn this type of confirmation-before-posting functionality on.
