To disguise your users details like IP, email client, etc. we have to create a new file in `data/conf/postfix/mailcow_anonymize_headers.pcre` and insert the following:
|
|
|
|
```
|
|
/^\s*Received:.*Authenticated sender:(.+)/
|
|
REPLACE Received: from localhost (localhost [127.0.0.1]) (Authenticated sender:$1
|
|
/^\s*User-Agent/ IGNORE
|
|
/^\s*X-Enigmail/ IGNORE
|
|
/^\s*X-Mailer/ IGNORE
|
|
/^\s*X-Originating-IP/ IGNORE
|
|
/^\s*X-Forward/ IGNORE
|
|
```
|
|
|
|
Next we need to add the following to `data/conf/postfix/main.cf`:
|
|
|
|
```
|
|
smtp_header_checks = pcre:/opt/postfix/conf/mailcow_anonymize_headers.pcre
|
|
```
|
|
|
|
Then restart Postfix:
|
|
|
|
```
|
|
docker-compose restart postfix-mailcow
|
|
```
