[H-GEN] Humbug SPF IPv6 records

[Paul Gear]

Hi folks,

Looks like there's an error somewhere in your DNS records, or possibly
in an unintended IPv6 configuration on excalibur.humbug.org.au.  I've
been getting these rejections in my mail logs:

It seems 2400:c401:1002:11:5054:ff:fead:f514 doesn't map to
excalibur.humbug.org.au in either forward or reverse DNS, so the SPF is
failing.  Could someone with the requisite permissions please fix?

Thanks,
Paul
