Postfix Strip Headers Not Working At All

Hi Experts,

Maybe it's because I've been awake since 1:30 AM, but somehow I am unable to get postfix to strip...  head... ers...  strip headers. ;)

Ok, heres the setup:

Home Mail Server -> Remote Relay Mail Server Proxy (both postfix)

I want to strip all "Received" headers from all smtp related email forwarded to my remote relay mail server proxy box so the forward relay box will be the originating box, instead of all my local lan IP addresses and amavisd scan headers and such.

I followed a bunch of ideas and guides but nothing has worked for me yet. Not sure what I'm missing.

Basically:

main.cf:
smtp_header_checks = regexp:/etc/postfix/smtp_header_checks

and in /etc/postfix/smtp_header_checks I have:

/^Received/   IGNORE

I think it could have something to do with the fact that I am relaying a message instead of receiving it? But I logically assume postfix would understand that I am still sending via SMTP to google or whatever...  I am confused as to why this doesn't work!

Thanks for any help! I hope there is an easy fix for this solution...

Best regards,

Received: headers are counted to prevent mail delivery loops

Normally you have already a file /etc/postfix/header_checks

In main.cf
header_checks = regexp:/etc/postfix/header_checks

in header_checks file ad regex replacing Received: with nonsense
/Received:\ .*\[127\.0\.0\.[0-9]/ REPLACE Received:\ from Intranet.

I figured out the reason, which is unique to my system so no point in posting my results.

Thanks for the help!
