+
+Three types of values are permitted:
+
+- nil: no Fcc header is added,
+
+- a string: the value of `notmuch-fcc-dirs' is the Fcc header to
+ be used.
+
+- an alist: the folder is chosen based on the From address of
+ the current message according to an alist mapping regular
+ expressions to folders or nil:
+
+ ((\"Sebastian@SSpaeth.de\" . \"privat\")
+ (\"spaetz@sspaeth.de\" . \"OUTBOX.OSS\")
+ (\".*\" . \"defaultinbox\"))
+
+ If none of the regular expressions match the From address, or
+ if the cdr of the matching entry is nil, then no Fcc header
+ will be added.
+
+If `notmuch-maildir-use-notmuch-insert' is set (the default) then
+the header should be of the form \"folder +tag1 -tag2\" where
+folder is the folder (relative to the notmuch mailstore) to store
+the message in, and tag1 and tag2 are tag changes to apply to the
+stored message. This string is split using `split-string-and-unquote',
+so a folder name containing spaces can be specified by
+quoting each space with an immediately preceding backslash
+or surrounding the entire folder name in double quotes.
+
+If `notmuch-maildir-use-notmuch-insert' is nil then the Fcc
+header should be the directory where the message should be
+saved. A relative directory will be understood to specify a
+directory within the notmuch mail store, (as set by the
