Well for the first time I have a message which was grey-listed which 
appears on the surface to have been properly resent but which never gets 
accepted for delivery. Here are some of the pertinent log entries:

Note that the last message was sent ~12 minutes after the first attempt. 
The greylister is setup to accept any properly resent message after 3 
minutes. For this particular message the greylister never accepts it 
even though everything (sender Email, recipient Email, sending server IP 
address and msgid). Now I know the greylister works for other messages. 
Why might it have failed for this message and how to I go about 
debugging it?

Thanks for your suggestions.
