Connect your domain on Porkbun
Porkbun's DNS editor in five records, including where the priority field hides.
Porkbun adds your domain to whatever you type
Enter names without your domain — _mailflat-verify, not _mailflat-verify.acme.com. Typing the full name stores it as _mailflat-verify.acme.com.acme.com, and no amount of waiting will make that verify. In the dashboard, keep the Provider dropdown on name only and use the copy button next to each Host.
Where the DNS editor is
- Log in to Porkbun

Field names here: Host for the record name, Answer for the value, Priority for MX priority.
The five records, as Porkbun wants them
Your real values are on Domains in the dashboard — the verification token and the DKIM key are unique to your domain. Everything else looks exactly like this.
| Type | Host | Answer | What it does |
|---|---|---|---|
| TXT | _mailflat-verify | mf-verify-… (yours is in the dashboard) | Proves you own the domain. Verification fails without it. |
| MX | @ | mail.mailflat.net.Priority 10 — Priority | Routes incoming mail to MailFlat. |
| TXT | @ | v=spf1 include:mailflat.net ~all | Authorises MailFlat to send for your domain. |
| TXT | mail._domainkey | v=DKIM1; k=rsa; p=… (yours is in the dashboard) | Signs your outgoing mail. |
| TXT | _dmarc | v=DMARC1; p=none; | Tells receivers what to do when a check fails. |
Porkbun specifics
Porkbun adds your domain for you. Leave Host empty (or @) for the root; use the short name otherwise.
The value column is called Answer.
Priority appears only after you pick type MX.
Then verify
Back on Domains, press Verify. If it fails, the message says what is actually wrong — including the case where your records landed one level too deep, with the exact name we found them under. DNS changes are usually visible within minutes; a failure that names a wrong record will not fix itself by waiting.
