24 | ;;; Commentary: |
| 25 | ||
| 26 | ;; Maildir format is documented at <URL:http://cr.yp.to/proto/maildir.html> | |
| 27 | ;; and in the maildir(5) man page from qmail (available at | |
| 28 | ;; <URL:http://www.qmail.org/man/man5/maildir.html>). nnmaildir also stores | |
| 29 | ;; extra information in the .nnmaildir/ directory within a maildir. | |
| 30 | ;; | |
| 31 | ;; Some goals of nnmaildir: | |
| 32 | ;; * Everything Just Works, and correctly. E.g., NOV data is automatically | |
| 33 | ;; regenerated when stale; no need for manually running | |
| 34 | ;; *-generate-nov-databases. | |
| 35 | ;; * Perfect reliability: [C-g] will never corrupt its data in memory, and | |
| 36 | ;; SIGKILL will never corrupt its data in the filesystem. | |
| 37 | ;; * Allow concurrent operation as much as possible. If files change out | |
| 38 | ;; from under us, adapt to the changes or degrade gracefully. | |
| 39 | ;; * We use the filesystem as a database, so that, e.g., it's easy to | |
| 40 | ;; manipulate marks from outside Gnus. | |
| 41 | ;; * All information about a group is stored in the maildir, for easy backup, | |
| 42 | ;; copying, restoring, etc. | |
| 43 | ;; | |
| 44 | ;; Todo: | |
| 01c52d31 MB |
45 | ;; * When moving an article for expiry, copy all the marks except 'expire |
| 46 | ;; from the original article. | |
| 23f87bed MB |
47 | ;; * Add a hook for when moving messages from new/ to cur/, to support |
| 48 | ;; nnmail's duplicate detection. | |
| 49 | ;; * Improve generated Xrefs, so crossposts are detectable. | |
| 50 | ;; * Improve code readability. | |
