Opening Ports and Forwarding Ports on The ASA5510

So I am trying to open ports 443, 22 and 25 on the ASA5510.  I then want to forward all external traffic coming on ports 22 and 25 to a spam appliance and 443 to my mail server.

I have created the following objects

Network
-----------
T1 - External IP
SB - Spam Box
MA - Exchange Box

Service Groups
-------------------
Mail - TCP port 443
Spam - TCP port 22, 25

I created the following Access rule:  I think this opens up 25, 22, and 443 to the outside.
Source ANY, Destination T1, Service: Mail, Spam, Permit

Now I am unsure how to forward these. I am trying with a Public Server Rule

For the public server I am trying to add a rule to forward all 25 and 22 traffic to my spam box:  

private interface:  Management (basically my internal gateway)
Private Address:  SB (spam box object)
Service: Spam
Public Interface: T1 (external IP)
Public IP:  ?  if I put our external IP it says they cannot be the same.

Also, is a public server rule the right way to forward this info?

Thanks,
JOe K.

This is killing me.  I'm trying to change the address of the Management Interface because it's interferring with my Inside Interface.
