Disable emails for test forum

We're preparing to make the switch from vBulletin to xenForo. We have a large forum and I'm anxious about the import. So before I make the switch on my live forum, I want do a test run import to my test xenForo forum (which I have installed and ready on my server).

On my test vBulletin forum, I disabled all emails so my forum members wouldn't be getting emails from the test forum. I haven't been able to find a way to do this for xenForo. Anybody know how?
Hmm, maybe I am answering my own question, but since there are no birthday emails in xenForo and we are not going to be making any posts to the test forum, maybe there won't be any emails that would need to go out anyway? Are there any other emails that would go out?
