Thanks for that. So what exactly would you be able to use this for?

For one example, this would certainly take care of a lot of the work necessary for creating a disposable email service.

One existing use-case is Facebook's 'reply to this email to post a comment' feature.

It's actually for an application that needs to receive an email.
