Trend Micro™ Deep Discovery Email Inspector™ stops sophisticated targeted attacks and cyber threats by scanning, simulating, and analyzing suspicious links and attachments in email messages before they can threaten your network. Designed to integrate into your existing anti-spam/antivirus network topology, Deep Discovery Email Inspector can act as a Mail Transfer Agent in the mail traffic flow or as an out-of-band appliance silently monitoring your network for cyber threats.
2.1 Risk Level Enhancement
Deep Discovery Email Inspector highlights the risk of unknown threats to help security administrators focus investigation on high-risk threats.

The Virtual Analyzer sandbox environment opens files, including password-protected archives, and URLs to test for malicious behavior. Virtual Analyzer is able to find exploit code, Command & Control (C&C) and botnet connections, and other suspicious behaviors or characteristics.
3.6 Email Attachment Analysis
Deep Discovery Email Inspector utilizes multiple detection engines and sandbox simulation to investigate file attachments. Supported file types include a wide range of executable, Microsoft Office, PDF, web content, and compressed files.
3.7 Embedded URL Analysis
Deep Discovery Email Inspector utilizes reputation technology, direct page analysis, and sandbox simulation to investigate URLs embedded in an email message.

The following are known issues/limitations with Deep Discovery Email Inspector:
9.1 Hot Fix Required to Install Service Pack
Problem: Due to the file size, Deep Discovery Email Inspector 2.0 Service Pack 1 cannot be applied on 2.0 GM build without Hot Fix 0004.
Solution: Apply Hot Fix 0004 on Deep Discovery Email Inspector 2.0 Build 1223 before upgrading to Service Pack 1.
9.2 Widget Preferences Do Not Migrate
Problem: After applying Deep Discovery Email Inspector 2.0 Service Pack 1, widget preferences do not migrate (examples: layout, refresh interval, and threshold).
Solution: Reconfigure your widget preferences.
9.3 Unable to Install if an IP Conflict Exists
Problem: Deep Discovery Email Inspector cannot successfully install if an IP conflict exists. The Deep Discovery Email Inspector appliance has a default IP address (192.168.252.1). If another endpoint uses the same IP address, Deep Discovery Email Inspector cannot start services.
Solution: Trend Micro recommends not connecting the appliance to the network until after the default IP address has been changed to a unique IP address on the network.
9.4 Virtual Analyzer Unable to Import Images from FTP Servers in Active Mode
Problem: Deep Discovery Email Inspector is unable to import Virtual Analyzer images from an FTP server in active mode. Deep Discovery Email Inspector security does not allow this type of connection.
Solution: Trend Micro recommends using FTP servers in passive mode, or importing the Virtual Analyzer images through another method.
9.5 Limited Support for Email Messages in Non-Standard Formats
Problem: Deep Discovery Email Inspector cannot read the subject of email messages in non-standard formats.
Solution: Trend Micro recommends only routing standard-formatted email messages. Most mail user agents cannot read email messages in non-standard formats.
