So I set Xenforo up that when a user registers, he has to confirm his email account before the account gets activated. However Xenforo is linked to Google Apps, which has a limit of 2000 emails per hour. I have seen in the Xenforo Server Logs that the limit has been reached a few times. What happens with the emails that request the user to confirm their account, when you are in period (or technical problem) where you can't send emails? Are they send at a later time? Does Xenforo try to send them out again later?
