unable to send emails for gmail

Mail records

If you’re using mail.mytastefactory.co.uk hostname to send emails, then I am afraid this particular DNS record at DNS tab of Cloudflare dashboard for your zone seems to be proxied :orange: as far as it’s returning the Cloudflare IP address, which indicateds a wrongly configured mail with Cloudflare. Therefore, the SPF record is failing as well.
