1. About Trend Micro Deep Discovery Email Inspector


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.

7. Known Issues


7.1. Unable to Receive Email Messages from Other IPv6 Subnets if "Hosts in the same address class" is Enabled

Problem: Deep Discovery Email Inspector cannot receive incoming emails messages from other IPv6 subnets if the "Hosts in the same address class" option is enabled on the Administration > Mail Settings > Limits and Exceptions screen.

7.2. Duplicate Time Value Appears on Widgets after Daylight Savings Time Changes to Standard Time

Problem: After daylight savings time changes to standard time on Deep Discovery Email Inspector, a duplicate time value appears on widgets.

7.3. Unable to Capture ISL-Encapsulated VLAN Traffic in SPAN/TAP Mode

Problem: While operating in SPAN/TAP mode, Deep Discovery Email Inspector cannot capture VLAN traffic that is encapsulated by Cisco Inter-Switch Link (ISL) protocol.

7.4. 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.

7.5. 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.

7.6. 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.
