I had posted some of this before but since I wasn't a valid subscriber
I was "silently" ignored.. mybad.. :-)

---
I have an internal relay that I am replacing (sendmail with postfix)
I have followed :
http://www.postfix.org/STANDARD_CONFIGURATION_README.html#firewall
and have my transport working with relay_host and transport maps.

Most everything goes out via the
relay_host =outbound.aaa.dom
but following Wieste's statement "transport ovrrides relay_host"
I have set up the exceptions that will relay out directly
and those are working correctly..

What isn't working is the ability for root to receive email for all the
"bounced / undeliverable" messages that are relay through this box.
I do have a user account that I want to receive "root's email" so I can
read via dovecot and an IMAP client.
I don't want all the messages coming to my work email account..

What happens is that the message To
root(a)zzz.aaa.dom
goes directly out the relay_host..

I have tried

Particulars

- The current box relays about 30k messages daily.
- aaa.dom = my domain
- zzz.aaa.dom = my sub domain

here is the postfinger output..

Try to add zzz.aaa.dom to mydestination ...
