pmx_log does not present each message as a one-line summary, but rather records debug, info, notice, warning and error messages from the
pmx-milter process. You can adjust the verbosity of this log.
What to do
To make the PureMessage system log more verbose, in the
/opt/pmx/etc/pmx.conf file, increase the setting for the
debug_level to 3 or greater. For more information, see the
pmx.conf man page.
Note: Increasing the
debug_level could noticeably slow mail throughput on heavily loaded servers, particularly when it is set to a value greater than 2.
