You can always add an extra header that contains what you want. (Exim's
default for that is Return-path:). The From_ line in mbox is used as a
message delimiter. AFAIK it's not even treated like a header, so it's
not sent to the (POP3/IMAP-)MUA.

Don't know about that, probably better to ask Sam Varshavchik on the
One reason probably is because it's easier to get a complete folder list
by scanning a single folder than recursively scanning all folders.
The starting dot '.' is clear, I guess, otherwise you couldn't have
folders named cur, new and tmp.
