update: the sender is generate more or less similar messages.
most of them pass, but only some fail. If they fail, there is  
everytime the 5 second delay visible.
I suspect temporary DNS trouble. I'll extend OpenDMARC's DNSTimeout  
[1] to something other then 5 seconds
to make sure I'm searching on the right place...
