Forwarding is done by a MySQL table called by virtual_alias_maps in
postfix. Any local mail is relayed to a Barracuda AntiSpam box and
forwarders are relayed to their mx's. All mail goes through a list of
rbls, greylisting (postfix-policyd) and clamav before relay.
At the moment there is only one domain going through this gateway, but
in the near future all our domains are going to be pushed through the
gateways.

Thanks
Guy
