Also tried to use a specific postfix logfile by settiing the following in main.cf:
maillog_file = /var/log/postfix.log
I didn't give me anymore logging.
The Cyrus LASL documentation says the followiing:
log_level (default: 1)
Specifies a numeric log level. Available log levels are:
0: Don't log anything 1: Log unusual errors 2: Log all authentication failures 3: Log non-fatal warnings 4: More verbose than 3 5: More verbose than 4 6: Traces of internal protocols 7: Traces of internal protocols, including passwords
Important Cyrus SASL sends log messages to the application that runs it. The application decides if it forwards such messages to the syslog service, to which facility they are sent and which priority is given to the message.
