question on my setup. my primary MX server sits inside my network, with a NATed

should i move this MX server outside and use it's public address in the config
? inbound mail gets checked and relayed to a content filter on another server.
mynetworks = 127.0.0.1/32,192.168.0.10/32,10.135.0.0/16
or am i fine leaving it behind the NAT ?
Postfix will work just dandy behind a NAT device, assuming a
sane NAT configuration that allows postfix to log the real
remote client IP and not the NAT device IP
You should add your external IP to the proxy_interfaces
parameter. Postfix uses that for loop detection and to accept
mail to postmas...@[external.ip]

# main.cf
proxy_interfaces = public.ip.address.here
