I have a stage.domainX.com and domainX.com. How do I adjust the MX records accordingly to where all mail sent to stage.domainX.com goes to one server (IP1 66.xx.xx.xx) and all other mail sent to domainX.com goes to another server (IP2 67.xx.xx.xx)?
info@stage.domainX.com -> IP1
info@domainX.com -> IP2
