ok, guys.
here is the flow.
fqdn of my main mailserver -- qmail.domain.com - it is the main ip of the server
fqdn of my postfix on the main server, which does my spam filtering -- postfix.domain.com, it is eth0:1.
both are bound to their IP - and do not seem to conflict.
fqdn of a second mail server - qmail2.domain.com
Scenario : we update the mx record on a domain to be "postfix.domain.com". it comes in, cleans it, and is to relay it to qmail2.domain.com. instead, it is passing it to qmail.domain.com, which replies, this domain doesnt exist. it needs to be finished sending out by postfix.domain.com, and to the IP I specify - so it relays properly.
where or how does postfix relay/transport?
