I am a bit puzzled about this one, we had some reports of the problem
so far, which hasn't occurred before on any other dyne list and is not
really reproducible.

what we notice is that our mail server is under some quite heavy load
and we are working to move it to a bigger infrastructure by september

however it is highly available already and seems to process
everything, so I'm not really sure what is happening... any insight is
welcome.

ciao!
