Cafe24 Domain Email Setup: MX, SPF, and DKIM in Order
A practical Cafe24 guide from nameserver checks and MX changes to a single SPF policy, DKIM verification, and external send-and-receive tests.
First confirm where DNS is actually managed
Even if the domain was purchased from Cafe24, records must be changed at another provider when the nameservers point there. Confirm the current nameservers, then record existing mail-related entries before editing DNS.
Change MX and SPF without conflicting records
Leaving old-provider MX records beside the new MX can split delivery. Publish only one SPF policy at the root domain; if another sender is still needed, merge its authorization with OfficialMail into that policy.
After DKIM, test both directions externally
Enter the current DKIM public key exactly as shown in domain setup. Even after verification succeeds, test inbound and outbound mail with Gmail or Naver and confirm SPF and DKIM show pass in the message source.
Start with OfficialMail
Start operating with one official primary mailbox.
Use one primary mailbox as your company's official address and review every domain-connection value directly in the mailbox.
