Well spotted Greg ;-)
As it happens, I have MX records pointing at relay.iuinc.com. The
``awfulhak.org'' ``A'' record is the same as the ``www.awfulhak.org''
``A'' record - and that's a machine that tells the connecting http
client that I've moved to www.awfulhak.demon.co.uk. It does this for
loads of other domains too.
As a result, sending to the ``A'' record will cause a bounce !
