SPF Record Configuration for Secure Email Delivery
To ensure high email delivery rates and maintain a good domain reputation, it is essential to properly configure the SPF record in your domain's DNS.
The SPF (Sender Policy Framework) record specifies which IP addresses or mail servers are authorized to send emails on behalf of your domain. This helps recipient servers to verify the authenticity of incoming messages and reject those sent from unauthorized sources.
Why it's important
A correctly configured SPF record:
- Helps prevent email spoofing
- Improves email deliverability (avoids spam folders)
- Protects your domain reputation
SPF Parameters for Utixo Cloud Services
If you're using Utixo Cloud services, configure the following DNS record:
- Record type: TXT
- Hostname:
yourdomain.ext.(include the final dot) - Value (Text):
"v=spf1 +a +mx include:spf.utixo.net ~all" - TTL: 3600
This setup authorizes the following servers to send emails:
- Your web hosting server
- The receiving MX server
- The IP address pool listed in
spf.utixo.net
SPF Syntax Note
The ~all directive is a soft-fail, meaning mail from other sources will be marked as suspicious but not outright rejected.
To strictly reject all unauthorized senders, use -all instead for a hard-fail policy.
