I’m receiving a lot of emails from my hosting provider like this:
This mail is unauthenticated, which poses a security risk
to the XXX sender and Gmail users, and has been blocked. The sender
must XXX authenticate with at least one of SPF or DKIM.
I already got the SPF record from my hosting provider some time ago and added it to Cloudflare.
v=spf1 a mx ipX:XX.XX.XX.X/XX ip4:XXX.XX.XX.X/XX ip4:XX.XX.XXX.X/XX ipX:XX.XXX.XX.X/XX ~all
However, emails are still getting blocked and apparently the SPF record is not provided.
I’m grateful for any tips or suggestion!
