There's a "From" field at the very top, without a colon.

I'm not trying to argue, but instead trying to check what I thought was my knowledge: AFAIK, that From header is what I call the mbox header--it is added in . for the mbox style of mail storage (many emails in one folder) and is used to separate emails). Two things: ' * in the other type of email storage (maildir--one email per file), I suspect that header is not added * I suspect that not all email clients put the same thing (the perceived sender address) in that second field (between "From " and the date). If anyone can speak to those points, I'd be interested.
