Abstract
Technologies are described related to third party email signature generation and authentication. A DKIM signature may be stamped in a way such that the 'From' address is encoded in the selector. The domain may be extracted from the DKIM signature based upon being from a known sender in the d=field, which signs on behalf of another domain. The reconstructed domain may be aligned from the selector against the actual domain in the 'From' address to pass DMARC.
