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 ! > Greg > -- > See complete headers for address and phone numbers > finger grog@lemis.com for PGP public key -- Brian , , Don't _EVER_ lose your sense of humour....
