{client_addr} returns SMTP client's IP address not Postfix's
interface IP address. So we can't use it as {if_addr}
replacement.

milter manager 1.6.5 (*) can solve it. :)
(*) http://milter-manager.sourceforge.net/

milter manager is a meta-milter. milter manager works
between MTA and milters:

                                   <-> milter1
  MTA (Postfix) <-> milter manager <-> milter2
                                   <-> milter3

milter manager can set any milter macros. They includes
{client_addr}.

                                   <-------------> milter1 (milter-greylist)
                                    {client_addr}
  MTA (Postfix) <-> milter manager <-------------> milter2
                    {client_addr}   {client_addr}
                        (new!)     <-------------> milter3
                                    {client_addr}

milter manager uses netstat(8) and SMTP client's IP address
and port for resolving MTA's interface IP address.


If you follow the install documentation, you can use the
above configuration:
