When this was discussed some time ago a workaround was implemented for
w32. I think this can be used on most platforms.

With this workaround you can edit the data in both Emacs and the mail
client. When you finish editing the mail message in Emacs the users
mail client is started to edit a new mail message. This message has
the subject from Emacs, but the body just says

   *** E-Mail body has been placed on clipboard, please paste them here! ***

This is implemented in mailclient.el
