How to Set Up SPF for Pobox?

SPF is a system that works as a layer in the mail transfer chain. It defines rules for accepting and rejecting mail based on the source of the message. For example, if an ISP wants to prevent senders from their network from sending emails claiming to be from their customers, they can publish a record giving details of the hosts and networks that are permitted to send messages on their behalf.

Creating an SPF Record for Pobox

Here are the steps to set up SPF for Pobox :

  • 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 Pobox will have the following syntax:    TXT   v=spf1 -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 Pobox. If you do have an existing SPF record in your DNS, you need to modify it to include Pobox, as shown below:

Previous SPF record:  v=spf1 mx -all

Modified SPF record:  v=spf1 mx -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.
