emacs23 - emacs 23 on OS X: mailto links & calling compose-mail? -

I'm trying 23.2 release coco amax build (OS X 10.6). There are many things that are more troubling about the Koko MACS than the harsh carbon amaxes (based on an Amaze 22 build, I believe), so I hoped that people have some solutions / ideas (unfortunately neither Can not post on the list of Carbon-MX, nor Emacs-dev has prepared a useful answer, so I thought I would try the overflow for the first time):

• Firefox I can set preferences, applications, mailo content, type "use emac", it used to work in carbon amax. Now when I click on the Firefox mailto link, it focuses on imex but in fact Nothing does anything

  In my .emacs the following are, which I think does not work in 23. suggestion?

 (setq browse-url-browser-function '(("^ Http:" browse-url-generic) ("https:". Browse-url-generic) ("Mailo:" lambda (url and rest of the stuff) (composition-mail (notification from 7)) ;; ("mailbox:". Browse-ur-mail) ;; same behavior ("^ file:. * \ I suspect that the emacs' '' '' '' '' The file is being asked to open 'failed' to find. To see what happens, try some things on the command line: 
 
  emacs mailto: example@example.com  
 
 Just open emacs and you  
 
  
 
  
 
  MX - aval '(browse-url "mail: user @ example.com")'  
 
 
 
 If all are checked out, then you need to wrap things up, when Firefox invented it (unless FF allows you to specify the command line using the% s replacement ). Alternatively, you might be able to work by setting TRAMP to understand a mailto: url, but it seems that is a bit complicated. 
 
 (Now I know what to see: you can find helpful.)
