Thanks for suggestion. I have created header_check filter with following but no success. /^Received:.*\[127\.0\.0\.1/ IGNORE /^Received:.*\[10\.2\.1\.83/ IGNORE /^Received:.*\[192\.168\.1\.[0-9]/ IGNORE

Be careful your rule is specific enough that you don't remove headers from outsider's mail. See postfix-users archives for examples. WARNING: removing internal IPs is seldom necessary and hides valuable debugging information. The public IP Received: header is added by the receiving system; that's the IP they receive the mail from. If your mail server has multiple addresses, smtp_bind_address can control which one is used. http://www.postfix.org/postconf.5.html#smtp_bind_address -- Noel Jones
