This pidgin-plugin implements xmpp message delivery receipts (XEP-0184 v1.2).

When no delivering confirmation is displayed, it is also possible that the receiver doesn't support the extension.

To compile the plugin, run

$ make

You will need pidgin development packages (link in ubuntu: libpurple-dev and pidgin-dev).

To copy the extension to your personal plugin folder (~/.purple/plugins) run:

$ make install

Now you may activate the extension within the pidgin settings.
