A couple years ago, we published a post on the proper configuration of SPF records when sending emails through our servers. Although not a default configuration, this is very important when you’re enforcing validation of SPF using “-all”. Due to some internal changes, the required entry has changed a little. Previously, you needed to add an A record for spf.gzo.com (+a:spf.gzo.com) and now you’ll need to simply include spf.gzo.com (+include:spf.gzo.com). A screenshot of this entered correctly in cPanel is shown below.
For those with DNS hosted by us, your SPF record has already been updated with this change. If you’re not hosting your DNS with us, the existing A record will continue to function normally in the short term, but please be sure to make the necessary change. If you have any questions or concerns, please submit a ticket and we’ll be happy to assist.
