Exchange has a feature which allows you to limit the number of users that can be sent on a single mail message. You won't really be able to prevent them from sending, but you can make it as difficult as possible.
Send out a warning, letting people know the sending of Christmas cards is not condoned and a limit will be placed on the number of people that will be permitted on a message during this time of year. Once you've done that, reduce that number down to some ridiculous number like 3 or 5.
