A Sender Policy Framework (SPF) record is a type of Domain Name Service (DNS) that identifies which mail servers are permitted to send email on behalf of your domain (your email@domain.com). The purpose behind having a SPF record is to prevent spammers from sending messages with forged “From” addresses tied to your domain.
It is highly recommended that your domain's SPF record is updated to include the iMIS email server. The advantages of adding the iMIS mail server to your domain's SPF are the following:
- Sender reputation - Your sender reputation directly correlates with whether or not your emails are automatically marked as spam by email inbox providers, such as Gmail or Outlook. Your sender reputation also factors in to whether your emails are bouncing or being opened.
- Deliverability - Your ability to reach a subscriber's inbox increases.
Checking for a valid SPF record
Use one of the following sites to see if you have a valid SPF record:
If the resulting page contains the message states that no valid SPF records are found of either type TXT or type SPF, then your domain does not currently have an SPF. If your domain does have an SPF record, the results of the SPF record will be shown.
Contact your DNS provider and request to update the domain SPF. To obtain the public IP address for your iMIS site (your DNS provider will ask for the public IP address), please contact ASI Hosting.
