It had been a while since I created a new CNAME pointing to an external site and couldn't remember if I had to add the dot at the end of the external domain, so I set up CNAMES with and without the dot on two test sites. Now (yes, I did need the dot), that I have the new CNAME created on the live site I'd like to delete the CNAMEs from the test sites.
I don't seem to find an apparent way to do this, nothing in WHM appears to have a "delete this record" function. Any ideas?
