How to Set Up SPF for TrendMicro Hosted Email Security?

 

SPF is a TXT record published on your domain that allows specific servers to send mail by using your domain name. You will have to publish the SPF records through your DNS.



Creating an SPF Record for TrendMicro


Here are the steps to set up SPF for TrendMicro HES :

  • 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 TrendMicro HES will have the following syntax:

mydomain.com    TXT   v=spf1 include:spf.hes.trendmicro.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 TrendMicro HES. If you do have an existing SPF record in your DNS, you need to modify it to include TrendMicro HES, as shown below:

Previous SPF record:  v=spf1 mx -all

Modified SPF record:  v=spf1 mx include:spf.hes.trendmicro.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.
