R forwarded the following to me as Edward mistakenly attributed this to Camcycle rather than Cyclescape.
Your cyclescape spf record shows a:cyclescape.org, but if, as I suspect, you are using MB's email smart hosting, the SPF needs to include:_spf.mythic-beasts.com as that's the server that actually connects to the remote email.

Your cyclescape spf record shows
a:cyclescape.org
, but if, as I suspect, you are using MB's email smart hosting, the SPF needs toinclude:_spf.mythic-beasts.com
as that's the server that actually connects to the remote email.
