There isn't really much finesse involved. Messages start at the pattern "^From ". Any "From " inside of a message that would end up at the start of a line is changed to ">From ", so the pattern "^From " should be foolproof regarding splitting into messages. I don't remember what happens to "^>From " but consider it most likely that any "^>*From " inside of a message gets one ">" prepended when put into an mbox file, and one taken out again when displayed/processed. -- David Kastrup
