Transport Neutral Encapsulation Format (TNEF) is a Microsoft standard for
tunneling rich data over the Internet to a recipient. IBM Lotus Domino
uses the TNEF Converter feature (enabled with the setting of TNEFEnableConversion=1)
to extract file attachments from the TNEF stream and include the Rich Text
content inside the message. Diagnostic logging is enabled via TNEFDebug=1.
The amount of diagnostic logging can be controlled via TNEFConverter_Log_Level.
Values are as follows:
10: minimal -- log errors only
20: normal -- errors and terse info
30: informational -- errors, terse info, and some additional info
40: verbose -- provides all information
The TNEF Converter is built into the SMTP task. TNEFEnableConversion=1
must exist in order for TNEFConverter_Log_Level settings to take effect.
The default logging level is 20.
If TNEF conversion is enabled, reduce the amount of information logged
by setting TNEFConverter_Log_Level below 20.
This Domino feature became available in versions 6.5.6 and 7.02.
TNEFBreakSMIME, TNEFAttachRTF, TNEFKeepAttachment, TNEFEnableConversion
to messages received from the Internet are named as winmail.dat
