Hi,
i have tried something like this (in main.cf <http://main.cf>):
smtp_data_restrictions = check_lcient_acces cidr:/etc/postfix/add_header
and add_header file is like :
0.0.0.0/0 <http://0.0.0.0/0> PREPEND X-Send-IP:
${client_addr}
Perhaps you can do it with header_checks:
header_checks = pcre:/etc/postfix/header_checks
And the regexp something like...
/^Received: from .* \(.* \[([0-9\.]+)\]\).*$/ PREPEND X-Sender-IP: ${1}
no, this will add an X-Sender-IP for each received header found in the
message. you could prevent this by making the expression more "precise",
but Viktor suggestion is simpler and more robust.
