Sends notifications about new posts and replies on bbPress forums and allows replying to them simply by sending e-mail reply to notification message.

Unicornis

Reply to any post, forum topic and forum reply simply by sending e-mail reply. Now with file attachment support.
Plugin sends a notification message with customized Reply-to address, which enables to pass the reply to the correct place and post it to the WordPress. 
It strips away the quoted part of the message, so only the reply gets posted to the forum.
Requires Postmark account to hook the incomming emails.
Unique hash value in each message provides additional security.
