Default applications are stored as MIME associations in
~/.local/share/applications/mimeapps.list.

But if you need to start the default application for a file or a
protocol/URL, use GIO:
http://developer.gnome.org/gio/stable/GAppInfo.html#g-app-info-get-default-for-type
http://developer.gnome.org/gio/stable/GAppInfo.html#g-app-info-get-default-for-uri-scheme

(use "mailto" for the mail agent)
