Email DNS Records Explained

Your domain's DNS tells the rest of the internet where to deliver your mail and how to check mail that claims to be from you. Business email needs these records; the Email tab lists them with their status.

Record Name Value Why
MX @ 10 mail-api.ngdomain.ng Delivers incoming mail to your mailboxes
TXT (SPF) @ v=spf1 include:amazonses.com ~all Says which servers may send as your domain
CNAME (DKIM) ×3 <token>._domainkey <token>.dkim.amazonses.com Publishes the keys your outgoing mail is signed with
MX bounce 10 feedback-smtp.us-east-1.amazonses.com Handles bounces for your outgoing mail
TXT bounce v=spf1 include:amazonses.com ~all Lets the bounce address pass SPF too
TXT (DMARC) _dmarc v=DMARC1; p=none Tells other providers what to do with mail that fails the checks
CNAME autoconfig, autodiscover mail-api.ngdomain.ng Optional: helps mail apps set themselves up
SRV _imaps._tcp, _submissions._tcp mail-api.ngdomain.ng Optional: the same, for other apps

The DKIM tokens are unique to your domain; copy them from the Email tab.

Things to know

  • A domain can have only one SPF record. If you already send mail through another service, add include:amazonses.com to that record instead of creating a second one. Fix DNS does this for you.
  • Remove MX records from a previous provider. While they remain, some mail goes there instead.
  • Start DMARC at p=none. Once all your mail passes, you can move to quarantine or reject.
