how does Letters know which email address you do want

By looking at the headers of the message.

X-Original-To (if present) or the top-most Received header.

Received: from frida.dreamhost.com (frida.dreamhost.com [66.33.206.23])
        by mail.covisp.net (Postfix) with ESMTP id 09490118AC4A

This would be great for me as I subscribe to some lists with a +address (like kremels+listname) and it's a pain to have to manually add every single + address, and then having to select it from the list of dozens every single time you reply.

Assumign that Letters folds headers internally, it's a dead-simple regex

^X-Original-To: (.*)

or

^Received:.*by $SMTP_SERVER.*for <([^>]+)>
