Hi,
I using a Graylog appliance success to receive mail log send from the mailcow server without problem, I would like to the log message can output more details such as mail subject, I know postfix can use use the smtp_header_checks to do this, and I updated the syntax “ :/subject:/ WARN” to the postfix file “anonymize_headers.pcre” , this is allowed and how to reload this file ? or restart the postfix container should be ok ?
Thanks
