    i have postfix set on centos 6.6 and i have a problem when sending mail with ipv6 (see example : mail-tester(.)com/web-pfs3z )

    when i send mail with ipv4 , it send with no problem , but when i try sending with ipv6 , my ipv6 appears in the Received in the header but the originating ip is always the ipv4

    i've tried it on yahoo & comcast and they both gave the same results

    any idea how i can fix this ?
