+This container outputs the Postfix mail log to stdout by default, additionally logs are saved to `/var/log/s6-maillog/current` which is rotated every 10MB with only 3 log files retained.
 
 If you want to output somewhere else you can set environment variable `LOGOUTPUT`. For example `LOGOUTPUT=/var/log/maillog`.
 
 When enabled OpenDKIM only supports syslog output, the syslogd daemon is only used for OpenDKIM. Only /dev/stdout is supported for OpenDKIM syslog logs.
 
-_Note: the postfix exporter only works when the logs are left at /dev/stdout. This requirement of logs going to /dev/stdout is due to the containers logging structure. This may be improved but was needed to keep with backwards compatibility without adding additional variables to configured_
