Introduction to SPF - What is it and why do I need it?
If you are configured to use Mailprotector for your outbound email scanning, it is necessary to modify your DNS settings to include Mailprotector IP ranges as valid ranges for your domain to deliver from. Many mail servers, world-wide, require valid SPF records.
Note: This SPF record should only be deployed if your domain is using a Mailprotector hosted solution, or if you are relaying mail out via Mailprotector. Use of this SPF record on domains which are not sending mail via Mailprotector may result in mail being rejected by receiving servers.
Include in your SPF TXT file:
SPF records are published in DNS as TXT records:
|United States||"v=spf1 include:spf.us.emailservice.io -all"|
|Europe||"v=spf1 include:spf.eu.emailservice.io -all"|
|Asia Pacific||"v=spf1 include:spf.ap.emailservice.io -all"|
