News: Feature update
SPF (Sender Policy Framework) authentication for inbound email is now available in Sophos Email, and a great way to cut down spam and phishing attacks by blocking spoofed email.
Activate SPF in your Sophos Email policy with a simple toggle switch and we will begin checking the IP address of email senders against a list of authorized IP address published in the sending domain’s DNS record. If the IP address is not in the authorized list and if the senders SPF policy is FAIL, the email is rejected.
ETA for Sophos XG?
