Ok, after talking with support last night I have realized that astaro doesn't seem to know how their own product works. Here is my situation and what I think the solution is. I haven't tried it yet because I figured I would ask first before I get more frustrated.
-------------------------------------
-- Basic info and setting desires
-------------------------------------
Important Public IPs:
astaro - x.x.x.226
jane.com email server - x.x.x.240
john.com email server - x.x.x.230
1. We want spam to be filtering inbound.
2. We want email to send direct from servers (read: send with correct Public IPs).
3. We don't care about outgoing scanning.
4. Want email to be directed to the correct email server for its domain.
------------------------------------------------------
-- What I've tried and why I don't think it worked
------------------------------------------------------
-----------First Setup-------------------
SMTP Proxy: Transparent
DNAT rules for Both servers mapping public to private ips
NO snat rules
One domain profile
Host based relay enabled for both private email IPs
========Result===================
1. Spam Filtering Worked.
2. Email always was relayed through gateway and sent with astaro public IP.
3. Outgoing mail was scanned for spam
4. All emails went to one exchange server which dispersed email automatically to the correct exchange box
