Is it possible to set a NS record for a sub domain?
I registered my domain with namecheap.com and is fully hosted by Dreamhost. I created a subdomain on DH webpanel.
Now I want to use a 3rd party autoresponder/ezine system with this sub domain. This company told me that I need to set NS record points to them (ns1.y-ml.com. & ns2.y-ml.com.) or edit DNS in order for the system to work. They do not recommend setting IP directly for A record or MX record.
I'm new to this and I don't even know if it's possible. Can anyone help me?
