+\r
+I actually do something like this.  It's not everything Sebastian was\r
+looking for, but it's very simple, and works great for me.\r
+\r
+I use a combination of a "pending" tag and a "byYYYYMMDD" tag.\r
+\r
+>From cron, I run the following to refile pending mail back to the inbox\r
+when it comes due:\r
+\r
+#!/bin/bash\r
+DATE_STR=$(date +'%Y%m%d')\r
+notmuch tag +inbox -pending -by$DATE_STR -- tag:by$DATE_STR\r
+\r
+and in Emacs, I use the following key binding to snooze mail (or in the Mutt\r
+terminology I borrowed, `postpone' it, hence the key):\r
+\r
+(define-key notmuch-search-mode-map "P"\r
+  (lambda ()\r
+    "postpone message (remove inbox tag, add pending tag and refile date)"\r
+    (interactive)\r
+    (let* ((date-string (format-time-string "%Y%m%d" (org-read-date nil t)))\r
+          (date-tag (concat "+by" date-string)))\r
+      (notmuch-search-tag `("-inbox" "+pending" ,date-tag)))))\r
+      \r
+(The `org-read-date' function gives me a nice easy way to pick a date\r
+from a calendar.  I bind "P" to the same function in\r
+notmuch-show-mode-map, too.)\r
+\r
+Hope that helps!\r
+\r
+Best,\r
