Removing mailinabox glue records when using cloudflare

Currently we are using Cloudflare for DNS for our mailinabox installation and it works properly. With that said can we remove the glue records of mailinabox in our domain that are required from the default installation?

Yes, absolutely! The glue records are only necessary when there will be name servers present on the domain itself. With using Cloudflare for DNS there is no need.
