Reply by email?

[Antun]

Is there a mod out there that lets you reply to a thread by replying to an email, so that heavy users of forums can respond directly from their email inbox? Here's what I'm imagining:

1. User A subscribes to a thread (or is set up to receive all emails).
2. Third party (user B) replies to above thread.
3. This generates an automatic email to user A, which includes the contents of the post.
4. User A replies to email.
5. This email gets picked up by a server somewhere, parsed, and the reply is added to the forum.

Anyone know of something like this? I searched but did not find one.
