When you enable SPF, mail servers are required to check if your domain is listed in the SPF record. If so, the recipient's email server will accept incoming mail from your server. Bullhorn recommends that you include them in your SPF record to eliminate spam.
Creating SPF record for Bullhorn
Here are the steps to set up SPF for Bullhorn :
- Login to your DNS management console
- Navigate to Tools & Settings > DNS Template or open your DNS Advanced Settings to add a new record (this part depends on the DNS host you’re using to host your domains)
- You need to edit the DNS TXT record related to SPF
- Bullhorn uses the following SPF “a” mechanisms:
a:outbound5.bullhorn.com
a:outbound3.bullhorn.com
a:outbound2.bullhorn.com
a:o1.email.bullhorn.com
If you don’t have an existing record for SPF, you can configure the following:
mydomain.com TXT v=spf1 a:outbound5.bullhorn.com a:outbound3.bullhorn.com a:outbound2.bullhorn.com a:o1.email.bullhorn.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 Bullhorn. If you do have an existing SPF record in your DNS, you need to modify it to include Bullhorn, as shown below:
Previous SPF record: v=spf1 include:spf.domain.com -all
Modified SPF record: v=spf1 include:spf.domain.com a:outbound5.bullhorn.com a:outbound3.bullhorn.com a:outbound2.bullhorn.com a:o1.email.bullhorn.com
-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.
