An SPF record (Sender Policy Framework) tells receiving mail servers which systems are allowed to send email on behalf of your domain. Without a correct SPF record, legitimate messages are more likely to end up in spam or be rejected.
With TripleZero iT you usually manage DNS via the customer panel or DirectAdmin. The steps below will help you set up a professional SPF policy.
Why SPF is important
- Reduces spoofing: third parties can less easily misuse your domain as a sender.
- Improves delivery to Gmail, Microsoft 365, and other providers.
- Together with DKIM and DMARC, it forms the basis of modern email authentication.
Add SPF record
- Log in to your domain's customer panel or DirectAdmin.
- Open DNS manager and search for existing TXT records with
v=spf1. - Preferably use one SPF record per domain. Multiple SPF records cause errors.
- Add a TXT record at the root (@) with for example:
v=spf1 include:mail.triplezenoithosting.example a mx ~all— use the include/host that communicates TripleZero iT for your package. - Save and wait for DNS propagation (often several minutes to several hours).
Common mistakes
- Multiple SPF records on the same domain.
- Too many DNS lookups (SPF has a limit of 10).
- Hard fail (
-all) while not all shipping systems are included yet.
