Hi Paul , Here is what I have from them
Hello Peter,
Thanks for getting in touch. The SPF record looks like it needs updating at the DNS provider's end. Please could you update the following record at your DNS provider's end:
Existing record:
v=spf1 +a +mx +ip4:185.145.156.30 ~all
Update to:
v=spf1 +a +mx +ip4:185.145.156.30 +include:relay.k.io ~all
You'll then need to allow time for the change to propagate. Any further issues please let us know!
Kind regards,
Jamie Larcom
