But, you don't need that to SEND mail to hotmail and yahoo from
their dedicated source IP adressess.

/etc/postfix/.master.cf:
    smtpx      unix  -       -       -       -       -       smtp
        -o smtp_bind_address=x.x.x.x
    smtpy      unix  -       -       -       -       -       smtp
        -o smtp_bind_address=y.y.y.y

/etc/postfix/transport:
    hotmail.com smtpx:
    yahoo.com   smtpy:

/etc/postfix/main.cf:
    transport_maps = hash:/etc/postfix/transport

And "postmap /etc/postfix/transport" whenever you change the file.
