MORE INFORMATION

X.400 Service

X.400 protocol events, such as submission and delivery reports.

Resource

Events related to the use of MTA resources.

Security

Events related to attempted security violations.

Interface

Communication among MTA components, between MTAs and between the MTA and XAPI clients such as the store, MSMI, and DXA. This includes RPC use.

Field Engineering

Internal debugging trace.

MTA Administration

Administration program access to MTA queues and routing information.

Configuration

The configuration of internal parameters and/or problems in one or more MTA configuration files.

Directory Access

Events related to the MTA's use of the directory.

Operating System

Events related to the MTA's use of Windows NT functions, such as thread creation and file operations.

Internal Processing

Events related to the internal operation of MTA application code. Error events in this category indicate serious problem in the MTA.

Interoperability

Tracks the binary content of protocol messages. Use this category and Interface to log stack traces and XAPI traces to MTADATA\AP*.LOG. NOTE: No additional events are logged to the application or EV*.LOGs when logging is turned up on this category.

APDU (Application Protocol Data Unit)

Tracks full P1 content (MTA send/receive) and fully encoded P1 APDU (communication between remote MTAs) to diagnose interoperability or conformance problems. Use this category and X.400 Service to log binary data to MTADATA\BF*.LOG. NOTE: No additional events are logged to the application or EV*.LOGs when logging is turned up on this category.

EV*.LOGs are text event logs. You can enable these logs by updating the following registry key:


   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeMTA
                     \Parameters\TextEventLogging

to a value of 1.
