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.

Regards

Ian
