No. Messages are delivered to separate files; to ensure a delivery doesn't use the name of an existing message (or interfere with a concurrent delivery), the filenames include a timestamp, the process id of the delivering process, and the name of the host where the delivering process is running. (See .) Example: "996962912.20703.multivac.cwru.edu". That message is considered to have the 'tick mark if the file ".nnmaildir/marks/tick/996962912.20703.multivac.cwru.edu" exists in the maildir. (See .) The cr.yp.to page describes another way of storing a more limited set of flags; nnmaildir does not do things that way at present, but for better interaction with other maildir readers, it might in the future (in addition to the current way). paul
