Transparent SMTP proxy - doing something wrong

I want to use Transparent SMTP proxying, as to change my MX would have me down to one MX record, instead of the 3 I have right now (2 from my ISP and they relay to me).

Well, I think I want Transparent.  My understanding of Transparent is no changes to DNS.  ASL watchs for a port 25 flow, captures it, checks it, tags it, sends it on.

So I enable Transparent SMTP proxy.

Nothing in Domain Groups
Nothing in Profiles and domain group assignments
Feature setting all default (nothing set)
Content filters all disabled
Spam Protection enabled
Threshold 1:  08 WARN
Threshold 2:  :[:P]lease select:: Reject  (I would ASSUME that T2 is NOT enabled)
SS whitelist empty
SMTP Auth disabled
Advanced Settings
    Only Dos protection enabled; all else defaulted.

So NO mail seems to come through to my internal server.

I disable Transparet SMTP proxy and everything starts working again.

OK what have I missed????

So let me see if I got it so far....

I create Domain entries. Since I host to domains, I create two of these, and include their sub domains

The I bet I have to set up profiles.

I can do it for both domains in one policy, it seems.

Oh wait, there is one host, that I do NOT want to deal with.

Do I set up a domain specifically for it and then tell ASL to skip it?
