If I don't make changes based on the updated requirements...

What if I don’t change anything - what can I expect?

    If a sender hasn’t already made changes to comply with Microsoft (and thus Gmail and Yahoo), they can expect to see a higher rate of bounces due to rejections for not meeting authentication requirements. Per Microsoft’s article, “The rejected messages will be designated as "550; 5.7.515 Access denied, sending domain [SendingDomain] does not meet the required authentication level."”
