+ "Determines the maildir directory to save outgoing mails in.
+
+ If set to non-nil, this will cause message mode to file your
+ mail in the specified directory (fcc).
+
+ It is either a string if you only need one fcc directory or a
+ list if they depend on your From address (see example).
+
+ In the former case it is a string such as \"INBOX.Sent\".
+
+ In the fancy setup, where you want different outboxes depending
+ on your From address, you supply a list like this:
+
+ ((\"defaultinbox\")
+ (\"Sebastian Spaeth <Sebastian@SSpaeth.de>\" . \"privat\")
+ (\"Sebastian Spaeth <spaetz@sspaeth.de>\" . \"OUTBOX.OSS\")
+ )
+
+ The outbox that matches a key (case insensitive) will be
+ used. The first entry is used as a default fallback when nothing
+ else matches.
+
+ In all cases, the complete FCC directory will be constructed by
+ concatenating the content of the variable 'message-directory'
+ ('~/Mail/' by default and customizable via M-x
+ customize-variable<RET>message-directory<RET>) and this value.
+
+ You will be prompted to create the directory if it does not exist yet when
+ sending a mail.
+
+ This function will not modify the headers if there is a FCC
+ header, but will check that the target directory exists."
