How to Set Up SPF for Barracuda Email Security Service?

Enabling SPF makes it so that mail servers are required to check if your domain is listed in your SPF record. SPF or Sender Policy Framework is a way for an administrator to help prevent spam. If the sender's IP address doesn't match the IP address in the SPF record, your mail server will reject the message and any associated spam checks that you have set up will be passed.

Creating SPF record for Barracuda Email Security Service

Here are the steps to set up SPF for Barracuda Email Security Service :

  • Login to your DNS management console 
  • Navigate to Tools & Settings > DNS Template
  • You need to edit the DNS TXT record related to SPF
  • The include mechanisms for different countries are as follows:
  • An SPF TXT record for Barracuda Email Security Service 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 Barracuda Email Security Service. If you do have an existing SPF record in your DNS, you need to modify it to include Barracuda Email Security Service, 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
