I was asking what was the motivation for not having the envelope From in the Maildir format, as defined in the qmail spec :
"The message is delivered without an extra UUCP- style From_ line, without any >From quoting, and without an extra blank line at the end."
which may sound silly since we lose an important piece of information.
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.
Same question about the motivation in Courrier (Maildir++) for emulating a hierarchy for subfolders (like in .folder.subfolder.subsubfolder) instead of (note : I know about layout=FS, I'm not talking about that) implementing a real filesystem hierarchy.
Don't know about that, probably better to ask Sam Varshavchik on the Courier list. 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.
