NSF has applied a mandated global email policy change that may be interfering with NSF communications to and from external email recipients. All email activities may be impacted, including automatic NSF email notifications, ad-hoc review requests, panelist correspondence, and any correspondence with PIs, co-PIs, fellows and job candidates.
This new email validation system, called “Domain-based Message Authentication, Reporting & Conformance” (DMARC) is an email authentication, policy, and reporting protocol that helps to deal with phishing, spam, and server spoofing. This change was made as outlined in the Department of Homeland Security’s Binding Operational Directive (BOD) 18-01.
Since some universities, organizations, and federal agencies have not applied the DMARC policy for their email servers, email sent by NSF may be classified as spam by organizational email services and may be quarantined prior to delivery. Additionally, if an external email recipient auto-forwards email that is sent to their organization’s email account (ex. a .edu email address) to another account (ex. a gmail.com email address), they will not receive the forwarded email. A full explanation of this issue can be found on the DMARC website
Although there are no actions NSF or individual recipients can take to prevent emails from being blocked at this time, we strongly recommend following up emails with a phone call, especially if you don’t receive an expected reply. Additionally, please alert your IT Department or Email Administrator for information on ways your institution may be able to address the issue.
