Topic Last Modified: 2005-11-18
The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the value for the Rich Text Format (RTF) message antivirus scanning:
If the Exchange Server Analyzer finds the value for ScanPlainText is set to 0, a warning is displayed.
The ScanPlainText registry key is set by third-party antivirus vendors that use the Exchange Virus Scanning API (VSAPI). It is recommended that you scan all message types for viruses, including plain text messages. You should enable virus scanning of all messages flowing through an Exchange Server computer.
