Symantec Email Submission Client updated to support Exchange 2013

Symantec’s Email Submission Client enables end users to report suspected spam directly from their mailboxes to Symantec Security Response, which helps improve anti-spam research and results.  The Email Submission Client will be updated to support Microsoft Exchange Server 2013, and the new version is scheduled for release on March 28, 2015. Exchange Server 2010 and 2007 will also still be supported.

The Email Submission Client is designed to be easy to use and does not require the installation of tools or updates on endpoints. Users simply move the unwanted message to a designated folder in their mailbox to send the message to Symantec. Administrators control which users and groups in the organization can submit messages using Active Directory.

A moderated mode that allows administrators to approve messages before submitting them to Symantec is also available. The Email Submission Client works with multiple email clients, including Microsoft Outlook, Outlook Web Access (OWA), and Exchange ActiveSync.

Symantec Email Security.cloud customers can download the client from the management portal by navigating to Tools > Downloads.

Symantec Messaging Gateway and Mail Security for Microsoft Exchange customers can download the client from FileConnect at https://fileconnect.symantec.com
