Ryan, the choice is up to you. To start, you may want to download the Free Edition, install it and look around. Get comfortable with where things are, the interface, etc. We have well over 1,000,000 users on SmarterMail 16.x at this point, and well over 100,000 domains as well. Most major issues are resolved, and the .1 will be coming in a couple of weeks. Even if you decide to wait for that, it may still be worthwhile downloading the Free Edition and giving it a test run.
