Does my domain name need to be at BigPond for me to use BigPond Premium Mail?
No. Your domain name does not need to be located on the BigPond DNS (domain name servers), but your mailboxes must be hosted with BigPond. This works by pointing all of the ‘MX’ (mail) records from wherever the domain name is hosted to the mailboxes that reside at BigPond. Visit Domain Names to see what you have to do to redirect your MX records.
