Another option is to add a client restriction at the beginning that has: IMGATE_IP OK * REJECT postfix will reject all connections except those coming from the imgate IP.
A better way would be to use a firewall on that postfix server (I use PF on freebsd) and only allow connections to smtp from that one IP. Then all other connections would be blocked.
