Be aware that the server only saves send messages for a short amount of time. Because of that you can only use this to prevent duplicates in a short time-frame, older messages with the same ID are probably already deleted and the message will be send again.

Here is an example how such a scrippt could look like, you can put it into <code>/usr/local/sbin</code> and call it with <code>scn_send "title" "content"</code>
