Cloudflare email infrastructure

MX, SPF, DKIM and DMARC on Cloudflare: a migration map

Publish email records correctly and avoid proxying mail hostnames.

By Claire from Venmail

Publish email records correctly and avoid proxying mail hostnames. The safest starting point is to understand who controls the domain, what people need from email each day, and which parts must keep working while the change is made. Cloudflare, Cloudflare

A simple plan you can follow

Work through these steps in order

  1. 1

    Save the current records

    Copy the old MX and TXT values before making changes.

  2. 2

    Change one purpose at a time

    Set inbound MX, then add the sender's SPF and DKIM values exactly as supplied.

  3. 3

    Start DMARC carefully

    Use reporting while you identify every legitimate sender before enforcing a strict policy.

  4. 4

    Read a real message header

    Send outside the domain and confirm the receiver reports passing, aligned authentication.

Before you call the job finished

  • Only intended MX records remain
  • There is one consolidated SPF record
  • The active DKIM selector verifies
  • DMARC reports go to a monitored address
  • Mail hostnames are not accidentally proxied

Businesses using website forms, accounting systems and marketing tools across countries should list every sender first; a DNS record copied for one service can accidentally exclude another.
