ok cool, you will find that in touch is dumping all of the messages into the Db now, it used to store them on the Capita servers but no longer because of data protection, there is a simple size on disk script you can run to determine how much it is taking up, and there is also a patch which will delete all messages older than a year old, (patch 22749) from capita, but after running the patch you need to shrink the database manually to claw back the size on disk
probably best to speak to capita also
Size on disk SQL script, run via SQL management studio and execute against the sims DB
