this is mostly missconfiguration seen the before , but rare you can try to delete your dny ip from the header read .i.e for ideas http://blog.tenak.net/2011/04/2011-04-dont-send-client-ip-postfix.html you might mix it up with a special transport only matching that recipient domain i did some solution like this in master.cf transport buggyipcheck unix - - n - - smtp -o smtp_header_checks=regexp:/etc/postfix/buggyip_header_check /etc/postfix/buggyip_header_check /^Received: / IGNORE /etc/postfix/transport buggycheckdomain.de buggyipcheck: -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria
