What is SPF? SPF is short for "Sender Policy Framework," which is a method for helping to prevent email spam. It works as a type of DNS record that lists all the mail servers that are allowed to send email from a specific domain. If you do not have one, you should create one.

Creating SPF record for Crucial

Here are the steps to set up SPF for Crucial :

• Login to your DNS management console 
• Navigate to Tools & Settings > DNS Template
• You need to edit the DNS TXT record related to SPF
• An SPF TXT record for Crucial will have the following syntax: 

mydomain.com    TXT  v=spf1 include:spf.mailcluster.com.au -all

• Publish this record in your DNS records section for your respective domain. 

Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using Crucial. If you do have an existing SPF record in your DNS, you need to modify it to include Crucial, as shown below:

Previous SPF record:  v=spf1 mx -all

Modified SPF record:  v=spf1 mx include:spf.mailcluster.com.au -all

• Save changes 
• Wait for 72 hours to allow your DNS to process the changes 

Finally, you can look up your record using our SPF record lookup tool, and enable DMARC for your domains: take a DMARC trial.
