We have a private network on our lan and a public network on our lan. We want to put a mail gateway running postfix in the public network and have it be the point of entry and egress for the other mail servers also running postfix on both our public and private networks.
I can see here how to configure this: http://www.postfix.org/STANDARD_CONFIGURATION_README.html#local_network but I have a few questions. Are there any pointers or things I should watch out for when setting up this type of relationship? Also if mail is for a server on the private network is there any way for someone connecting by imap from the internet to authenticate and view mail (via phone or laptop with changing ip) on that server without resorting to a VPN app on a mobile device? Thanks! Cameron
