New specification for preventing phishing and email domain abuse likely to help email security, but will enterprises adopt it?

Google, Microsoft, Facebook, the Bank of America, and PayPal are among a group of 15 companies that have banded together to help fill a major security gap in email, today releasing a specification for curbing phishing and other abuses of legitimate email domains.

The new Domain-based Message Authentication, Reporting and Conformance (DMARC) is a framework for protecting email at the domain level so fraudsters can’t spoof a legitimate email sender’s account or domain for phishing or other nefarious purposes.
