DNS authentication records
Configure SPF, DKIM and DMARC so your mail is trusted.
Three DNS records tell the world that mail from your domain is legitimate. Without them, your messages are far more likely to land in spam.
SPF
An SPF record lists which servers may send mail for your domain. It is published as
a TXT record and authorises MXTerm’s outbound servers.
DKIM
DKIM adds a cryptographic signature to every outgoing message. MXTerm generates a key pair and gives you the public key to publish as a DNS record; receivers use it to verify the signature.
DMARC
DMARC ties SPF and DKIM together and tells receivers what to do when a message fails both — and where to send reports.
Tip
Start DMARC in monitoring mode (p=none) and review the reports before moving to
quarantine or reject. That way you catch legitimate mail sources before they get
blocked.
Warning
DNS changes can take time to propagate. Verify each record in the MXTerm dashboard before relying on it.
