Yahoo beefs up anti-spam defences
Yahoo said it will roll out globally this week a new antispam specification intended to make it easier for service providers to confidently discard suspicious email messages.
The specification, called DMARC (Domain-based Message Authentication, Reporting & Conformance), allows email senders to tell receiving services if they are using two other technologies to weed out spam.
Many email senders use DKIM, or DomainKeys Identified Mail, which wraps a cryptographic signature around an email that verifies the domain name through which the message was sent. The second technology, SPF, or Sender Policy Framework, allows email senders to indicate which hosts are authorised to send their email, allowing receiving organisations to discard messages coming from spoofed "from" addresses.
