SPF stands for Sender Policy Framework, and it specifies which mail servers are allowed to deliver emails for a domain. The SPF result will be verified against any outbound email after an SPF record has been established. The sending server is authenticated if it checks out successfully, otherwise, the receiving server labels it as spam. To enable SPF authentication, follow the steps:
Creating an SPF Record for Bluehornet
Here are the steps to set up SPF for Bluehornet :
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 Bluehornet will have the following syntax:
mydomain.com TXT v=spf1 include:bluehornet.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 Bluehornet. If you do have an existing SPF record in your DNS, you need to modify it to include Bluehornet, as shown below:
Previous SPF record: v=spf1 mx -all
Modified SPF record: v=spf1 mx include:bluehornet.com ~all
Wait for 24-48 hours to allow your DNS to process the changes
