Troubleshooting
Host field includes the full domain
Host field includes the full domain
Porkbun automatically appends your domain to the host field. Enter only the subdomain part — e.g.,
send not send.yourdomain.com.DKIM value too long to display
DKIM value too long to display
Porkbun may truncate long values in the list view, but the full value is stored. Copy the DKIM value directly from SendKit and paste it — it will work correctly.
