Don't know how to do RBLs and AV from postfix, but it doesn't take much
resources to accept and relay mail. Unless you have a helluva lot of it.

This is a fairly standard setup, if I'm reading you right. There's a
"smarthost" on the internet that accepts and relays mail for your
domain, example.com. Your LAN mail server goes and gets this mail,
usually via something like fetchmail, in a cron job if you like. The
cron job operates from the LAN mailserver and fetches the mail to that
server for distribution.
Am I missing something?

For this, you set up the default transport in postfix to smtp for the
host you're relaying to. In the transports file in your /etc/postfix
directory,
alfa :
bravo :
charlie local:
* smtp:mail.delta.com
The first two above are machine on the local network which will accept
mail and smtp connections with the relaying machine, charlie. Charlie is
the machine on which you're doing this. The last line specifies that all
other mail uses the smtp protocol to connect to mail.delta.com to
deliver mail elsewhere (your LAN mailserver).
After writing this file, be sure to db-ify it by running something like:
postmap hash:/etc/postfix/transport

Sorry if I've missed the mark here. I'm not exactly sure what you're
asking for. From the sound of it, it sounds like what most people do.
