Sirana SpamCenter is an end-user solution for spam management. It's used in conjunction with anti-spam engines such as the Microsoft Intelligent Message Filter for Exchange 2003/2007. With Sirana SpamCenter, messages that are identified as spam by the Exchange message filter are automatically added to a database, eliminating spam message buildup on the Exchange server.
Once they are added to the database, users can securely browse their quarantined messages through a Web interface. They can release messages that were blocked in error, eliminating the need for manual intervention by administrators. Users can also build personal Safe Sender lists and Blocked Sender lists to manage their quarantines automatically.
Version 2.3 includes support for retrieving spam from Exchange 2007 mailboxes, support for operating in multi-Active Directory domain environments, and geo-map reports that show where spam originates from.
