To Enable MTA Logging on a Specific Channel

1. Edit the imta.cnf file.

   The file is located in the /opt/SUNWmsgsr/config directory.

2. To enable logging for a particular channel, add the logging keyword to the channel definition. For example:

   channel-name keyword1 keyword2 logging

   In addition, you can also set a number of configuration parameters such as directory path for log files, log levels, an so on. See 25.4 Managing Message Store, Admin, and Default Service Logs

   Note –

   The message return job, which runs every night around midnight, appends any existing mail.log_yesterday to the cumulative log file, mail.log, renames the current mail.log_current file to mail.log_yesterday, and then begins a new mail.log_current file. It also performs the analogous operations for any connection.log* files. It is possible that mail.log_yesterday contains time stamps which have already passed over rotation time.
