Hi, Have a look at the "Received:" headers of each email. They are in reverse order. I.e. the one at the top is the most recently added. Take into account timezone differences too. 12 hours seems like a very long time for a delay. I suspect one of the receiving hosts in the chain employs greylisting, and the sending network employs many different sending servers (ie like Google) in a round-robin fashion. The greylisting server may not be configured to recognise the many different servers as one 'set'. All speculation of course ;) Feel free to send the headers off list and I'll take a look.
