Publish instantly by email (without going to WP admin)

I’ve used other CMSs that will send me an email containing the text of a pending post, along with an “Approve” or “Publish” link. Clicking on the link instantly publishes the post. No need to go to the admin first.

For me, this is a huge time saver, as I must currently process dozens of posts on a daily basis. It also allows me to quickly approve posts via my phone’s email client, even with a slow data connection.

So here’s my question: How can I create a link that will allow me to immediately publish a post, bypassing the WP admin altogether? Is this even possible?

(There’s a related thread here:

That thread has to do with comments, not posts. The “solution” posted by Ipstenu is not what I’m looking for. I really need to bypass the WP admin entirely.)
