DNS records explained: MX, SPF, DKIM, DMARC
What each record does and exactly what to enter.
After verification, your domain page lists the records below with your exact values and a status next to each one (OK, Wrong value or Not found). Press Check my DNS after changing anything. The examples here show the pattern; always copy the real values from your domain page.
MX: where your mail is delivered
MX records tell other mail servers where to deliver mail for your domain. A lower priority number is tried first.
| Type | Host / Name | Priority | Value |
|---|---|---|---|
| MX | @ (or your domain) | 10 | mail.jksoftwares.in |
Remove any old MX records from your previous provider, otherwise some mail will still go there. The backup server (if shown) takes over automatically when the main one is unavailable, and hands the mail on later.
SPF: who may send for your domain
A TXT record on the domain itself (@):
v=spf1 mx ~all
A domain may have only one SPF record. If you already have one (for example because you also send newsletters through another service), do not add a second one; merge them into a single line, such as v=spf1 mx include:_spf.example-newsletter.com ~all.
DKIM: a signature on every message
A TXT record named dkim._domainkey (the exact name is shown on your domain page) holding a long public key. Copy it with the Copy button. Some DNS hosts split long values automatically; others need them in one piece. If the check says Wrong value, make sure nothing was cut off.
DMARC: what to do with mail that fails the checks
A TXT record named _dmarc:
v=DMARC1; p=none; adkim=r; aspf=r;
p=none is the safe start: it only reports. Once your mail has been delivering correctly for a few weeks you can move to p=quarantine and later p=reject to stop other people forging your domain.
Optional: autoconfig and autodiscover
Two CNAME records (autoconfig and autodiscover) let Thunderbird, Outlook and phones find the right settings after you type only your email address and password. They are optional. If you use Cloudflare, set these two to DNS only (grey cloud), not proxied.
How long does it take?
Most changes are visible within minutes. Your provider's TTL value (often 1 hour) is the longest normal wait, and a few providers take longer. During that time, mail may arrive at either the old or the new place, which is why you should not switch MX before you are ready (see Move your existing email).
You can verify records yourself with any public DNS lookup tool, for example by searching your domain on a "MX lookup" or "DKIM checker" website.
