You can use Sender Policy Framework (SPF) to help prevent email spoofing. SPF enables you to define your sending hosts in a DNS record and lets recipients verify the authenticity of emails sent from those servers.
Creating SPF record for TRP (The Retention People)
Here are the steps to set up SPF for TRP :
- 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 TRP will have the following syntax:
mydomain.com TXT v=spf1 include:spf.theretentionpeople.com -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 TRP. If you do have an existing SPF record in your DNS, you need to modify it to include TRP, as shown below:
Previous SPF record: v=spf1 mx -all
Modified SPF record: v=spf1 mx include:spf.theretentionpeople.com -all
- Save changes
- Wait for 72 hours to allow your DNS to process the changes
