All emails from NGData has root@bestgrid30.math.auckland.ac.nz in From: field.

The reason of that is I created CNAME ngdata.auckland.ac.nz for data.bestgrid.org (bestgrid30.math.auckland.ac.nz) long time ago. And in revers lookup mail server finds bestgrid30 as a sender domain.

I've applied to move ngdata.auckland.ac.nz from bg30 to bg4.
