Microsoft Exchange Server 2013 With SP1-CRBS

Exchange Server 2013 Service Pack 1 (SP1) is now available for download! Please make sure to read the release notes before installing SP1. The final build number for Exchange Server 2013 SP1 is 15.00.0847.032. SP1 has already been deployed to thousands of production mailboxes in customer environments via the Exchange Server Technology Adoption Program (TAP). In addition to including fixes, SP1 provides enhancements to improve the Exchange 2013 experience. These include enhancements in security and compliance, architecture and administration, and user experiences. These key enhancements are introduced below.


  • Connection filtering: Messages are blocked from DNS RBL lists[6] or from manually specified IP addresses/ranges
  • Recipient filtering: Messages blocked when sent to manually specified recipients on the server (for intranet-only addresses) or to any recipients not on the server (stopping spammers from guessing addresses)
  • Sender ID filtering: Sender ID, a form of Sender Policy Framework (SPF)
  • Intelligent Message Filter: Initially a free Microsoft add-on, later, part of service pack 2, that uses heuristic message analysis to block messages or direct them to the “Junk E-Mail” folder in Microsoft Outlook clients.
