Note: CloudFlare now does this automatically. See http://blog.cloudflare.com/introducing-cname-flattening-rfc-compliant-cnames-at-a-domains-root. Need to use a CNAME at the root of your website at CloudFlare? Is that causing email deliverability issues? This should help. ------------------ --| High level |-- ------------------ This resolves the CNAME record to the associated A record(s), makes an API call to CloudFlare, and creates the necessary A record(s). This way you can have an A record at the root even if your host only provides you with a CNAME, and your email deliverability issues should be fixed. -------------------- --| Instructions |-- -------------------- 1.) Fill out the values at the top of the script. 2.) Run the script the initial time and verify you now have A records in place of the CNAME you previously had. Confirm it's working correctly. 3.) Schedule a cron job to run this script as often as you feel comfortable with. The suggestion being every minute.
