Will, my answers, but first, Brian made the changes for us. However, the mail host (GoDaddy.com) specified MX 10 and 50 for their mail servers and Brian used 0. I am concerned if that will work the same and why he did not use 10 and 50.
Can you be more specific? What's the domain in question and what are the entries you're seeing problems with?
Did our system let you add a CNAME for a record for which another record already existed? It shouldn't, so we should definitely fix that if that's the case.
Did you add these entries via the panel?
Do you have an entry that conflicts with one of the records we generate automatically, or did you add both entries?
