How to Set Up SPF for MessageLabs - Symantec (Broadcom)?

The Sender Policy Framework (SPF) is used to prevent spammers from sending messages on behalf of your domain. With SPF, publishing authorized mail servers enables end-users to validate incoming emails via a simple DNS lookup. Combined with DMARC, you can leverage it to decrease the amount of spam you receive and improve your deliverability.

Adding an SPF Record for MessageLabs - Symantec (Broadcom)

Allow Symantec Email Security to send messages on your behalf by adding them to your SPF record.

  • 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 Symantec will have the following syntax:    TXT    v=spf1 -all

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

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

Previous SPF record:  v=spf1 -all

Modified SPF record:  v=spf1 -all

  • Save changes 

  • Wait for 24-48 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 with our DMARC analyzer
