Microsoft 365 Email Senders Urged to Implement SPF, DKIM and DMARC
HelpNet Security, Monday, October 9,2023
In the wake of Google's announcement of new rules for bulk senders, Microsoft is urging Microsoft 365 email senders to implement SPF, DKIM and DMARC email authentication methods.
'These Domain Name Service (DNS) email authentication records verify that you are the legitimate sender of your email and prevent spoofing and phishing attacks,' Microsoft noted.
Google's upcoming spam-fighting measures
In February 2024, Google will introduce a number of new requirements for bulks senders, i.e., those that send over 5,000 messages to Gmail accounts per day.
Among other things, bulk senders will be required to keep spam rates below 0.3% and make sure that users can unsubscribe with just one click of the mouse, lest their emails end up blocked by Google or redirected to users' spam folder.
