I set up a friend with a TCH account a bit over 72 hours ago and though it seems that everything else is working properly, they do not receive email sent from my email (on a separate TCH hosted domain) and I do not receive theirs - all other email gets through. Instead we get the "Warning: message XXXXXX-XXXXXX-xx delayed 24 hours" email, with the X's consisting of a message ID.
