SPF (Sender Policy Framework) is an email authentication protocol that helps prevent unauthorized servers from sending emails using your domain. By specifying which servers are allowed to send on your behalf, SPF reduces the risk of spoofing and phishing.
This guide walks you through configuring an SPF record for Trustwave MailMarshal, a secure email gateway solution designed to manage and protect your organization’s outbound email traffic.
Note: If you’re already using Sendmarc for SPF management, copy the record that matches your region and follow the steps here.
Region | SPF Record |
---|---|
United States | v=spf1 include:spf.us.mailmarshal.cloud ~all |
Europe | v=spf1 include:spf.eu.mailmarshal.cloud ~all |
Australia | v=spf1 include:spf.au.mailmarshal.cloud ~all |
In this example, we will use USA’s SPF record as an example. To authorize Trustwave MailMarshal 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:spf.us.mailmarshal.cloud ~all |
Example of a new SPF record:
Host | Type | Value |
---|---|---|
@ or blank | TXT | v=spf1 include:spf.us.mailmarshal.cloud ~all |
Depending on your DNS host, allow up to 48 hours for DNS propagation.
