-@section Rich-text messages with @t{org-mode} (deprecated)
+You can also directly @emph{capture} such links - for example, to add
+e-mail messages to your todo-list. For that, @t{org-mu4e} has a function
+@code{org-mu4e-store-and-capture}. This captures the message-at-point
+(or header - see the discussion on
+@code{org-mu4e-link-query-in-headers-mode} above), then calls org-mode's
+capture functionality.
 
-It is possible to write rich-text messages using @t{org-mode}; see
-@url{http://orgmode.org/worg/org-contrib/org-mime.html}.
+You can add some specific capture-template for this, for example, to add
+a message to your todo-list, and set a deadline for processing it within
+two days, you could add this to @code{org-capture-templates}:
 
-Note, some earlier versions of @t{mu4e} had more elaborate support for

-well, this has now been deprecated; it might be replaced with something
