I have a site running at a subdomain that has been migrated to a new server and new domain name. To preserve search credits I know a 301 redirect is the proper way to handle migrating the transition.

Can I have a different mail server for each subdomain?

Basically, some GoDaddy DNS help text has me scratching my head. Godaddy's DNS service says, "You cannot set up your domain name to use more than one mail provider at a time."
