References not sent

Greetings! I entered my references last week, but I've checked with the folks I entered, and none of them have received an e-mail yet. (I asked them to check their junk e-mail accounts and they are not there.) All three of my references have the same domain name, and it is a .org address. I'm wondering if it got flagged for some reason, either by our server or on the Teach Away end. Please advise -- thanks!
