SPF (Sender Policy Framework) is an email authentication protocol that protects your domain from unauthorized use. It works by specifying which mail servers are allowed to send email on behalf of your domain.
This guide explains how to configure SPF for Netwide, a South African-based email and web hosting provider that offers SMTP relay and secure email delivery services.
Note: If you’re already using Sendmarc for SPF management, simply copy ‘include:spf1 ip4:41.76.177.0/24 ip4:41.76.181.0/16’ and follow the steps here.
To authorize Netwide to send emails on your domain’s behalf:
Example of an updated SPF record:
Host | Type | Value |
---|---|---|
@ or blank | TXT | v=spf1 include:another.net include:spf1 ip4:41.76.177.0/24 ip4:41.76.181.0/16 ~all |
Example of a new SPF record:
Host | Type | Value |
---|---|---|
@ or blank | TXT | v=spf1 include:spf1 ip4:41.76.177.0/24 ip4:41.76.181.0/16 ~all |
Allow up to 48 hours for DNS propagation, depending on your DNS host.
