i set up Mailcow-Dockerized and it works quite well.
Now I want to "Anonymize Mail headers" and so went through https://mailcow.email/dockerized/?c=IV.%20Usage%20and%20Examples&p=Anonymize_mail_header.md
I created "data/conf/postfix/mailcow_anonymize_headers.pcre" and added "smtp_header_checks = pcre:/etc/postfix/mailcow_anonymize_headers.pcre" to "data/conf/postfix/main.cf".
Now the Problem:
Logfiles show that every Mail is deferred because "pcre:/etc/postfix/mailcow_anonymize_headers.pcre is unavailable. open /etc/postfix/mailcow_anonymize_headers.pcre: No such file or directory"
What am i doing wrong?
I restartet the docker-container "postfix" several times, but the error persists.
Who can help?
