Just to reiterate, greylisting was *not* the reason why posts were
consistently delayed today. If it is felt that it is better left off the
server, then that's fine, I will concede and will keep it disabled.
The issue was always with *outgoing* mail from mailman and a flooded
mail queue, not a delay of accepting *incoming* mail which would have
only happened once for each MTA.
