i want to hide return path...

[Marcin <lfe@ghnet.pl>]

Hello,

I am using debian postfix. When a mail from the PHP (under apache) the mail header contain:
-------
Return-Path: <www-data@my.server.com>
-------

I want to hide only this ONE user.
It is possible ?

header_checks with:
/^Return-Path: <www/ IGNORE
/^Return-Path: <www-data/ IGNORE
/^Return-Path: <www-data@my.server.com>/ IGNORE

is not working :(
why ?
and how to ignore it ?

===

The best solution will be replacing
<www-data@my.server.com>
with for example
<blabla@my.server.com>

===

It is very important to me.

Thanks for any solutions.

The only idea is change postfix sources ? I just compiled postfix from
sources so this is not problem if it will help.
