Configure SMTP conversation logging
You can configure SMTP protocol conversation logging (logs the incoming or
outgoing SMTP protocol conversation when accepting or delivering a message).
If inbound logging is enabled, one conversation log is generated for each
inbound connection. If outbound logging is enabled, one log is generated for
each message delivery attempt.
The conversation log files are saved to the diagnostic files directory that is
defined during installation. The default location is <InstallDir>/queues/
diagnosticfiles, where <InstallDir> is the path of the top-level installation
directory, such as var/opt/SMSSMTP or C:\Program Files\Symantec\SMSSMTP.
Warning: SMTP Conversation Logging is disabled by default. Do not change this
setting unless you are instructed by Symantec Technical Support to do so.
