An SPF record can save your domain from spam and phishing by allowing you to keep a record of your authorized sources. 20i highly recommends their customers set up SPF for their respective domains. Here’s how you do it:
Adding SPF records automatically
You can make the SPF records get added automatically to all new hosting packages.
- Go to Account Preferences in My20i.
- Select Automatically add Stackmail's SPF record to my DNS zones and click Save.
Adding SPF records 'manually:
Firstly, access the DNS Management interface for your domain name. If the domain is registered with us, you can access this from the Manage Domains area of the control panel. If the domain is not with us but is assigned to a hosting package, you can reach this interface via the Manage Hosting -> Select Package -> Manage DNS section.
Towards the bottom of the Manage DNS page you will see 3 inputs to allow you to add new records. To add it:
- Leave the Name field blank
- Select TXT for Type
- Enter v=spf1 include:spf.stackmail.com a mx -all as data
- Then save the changes.Wait for 72 hours to allow your DNS to process the changes. Your domain is now protected by an SPF record.
You can use the same record for all domains that use our mail services, however it should be noted that the above record will tell external providers all of your e-mail should originate from our network. If this isn't the case the record should be updated accordingly. Enter v=spf1 include:spf.stackmail.com a mx -all as data
Finally, you can look up your record using our SPF record lookup tool, and enable DMARC for your domains to minimize spoofing attacks by taking a free DMARC trial.
