Hi guys, i have a reseller account, i want to change my email

i already change the email in WHM > List accounts > the primary domain > Change Contact Email

also in the hosting company WHMCS (the place that i bought this reseller account) > Client Area > My Details > Email Address

then i check my domain using domainwhitepages.com, but in the DNS records > email > its still says my old email address

please help, how to make the email in dns records changed to new email address, for current sites, and new sites that i will add again later
