PIX, NAT and PPPoE

[jfogg]

I am trying to configure a PIX 506E for home office use on ADSL. The provider requires PPPoE and dynamic addressing. I am able to do everything I need except create a translation to allow smtp inbound (I have a mail server inside). I just cannot figure out how to do a static translation to a dynamic address. I'm sure it's supported but I cannot figure out how.
