| Record | What it does |
|---|---|
| MX | Tells the world to deliver your domain's mail to MailHow. |
| TXT (SPF) | Authorizes MailHow's server to send mail for your domain. |
| TXT ×2 (DKIM) | Publish the public halves of your domain's signing keys, so receivers can verify your mail wasn't forged. MailHow signs with both a modern (ed25519) and a classic (RSA) key. |
| TXT (DMARC) | Tells receivers to reject mail that fails SPF/DKIM — protects your domain from spoofing and improves inbox placement. |
DNS changes usually propagate in minutes, but some registrars take up to an hour. "Verify records" re-checks live DNS each time you click it.
