Warnings in Email Preset Standard Security Policies

This week Microsoft added the warning banner "You don't often get email from..." to the standard preset email security policies.  While the warning would be ok if it was accurate, it is being put on almost every external email received.  Now there is no option to turn this alert off other than disable standard preset security policies.  Therefore, Microsoft has forced us to reduce security to stop this warning that is a complete nuisance.
