Postfix

What you need to do on Postfix side is to edit configuration according to the suggestions made in the Advanced Content Filtering above, but for your convenience, here is the quick version that could work for you too:

(/etc/postfix/)main.cf:
content_filter = scan:localhost:10025
receive_override_options = no_address_mappings

(/etc/postfix/)master.cf:
scan      unix  -       -       n       -       10      smtp
      -o smtp_send_xforward_command=yes
      -o disable_mime_output_conversion=yes

localhost:10026 inet  n       -       n       -       10      smtpd
      -o content_filter=
      -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks,no_milters
      -o smtpd_authorized_xforward_hosts=127.0.0.0/8
