I initially looked at the sender name and actual send time and when I didn't see anything fishy there I moved it to the email people. Sorry I didn't follow up. It may take time to find the source of the problem so don't hold your breathe.

The problem may be that your email provider didn't release the email to you until the next day, which is one usual culprit. I use to work for the email team, but now I'm in planning. I'll let you know when I hear something. In the mean time let us know if you receive the other email late, forward it onto me again and we'll add it to the ticket.
