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

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?
Cameron,
On your last question, sure you can do that - all you need to do is
map a public IP address/port to the private IP address/port, and
forward traffic for that public address/port combination to the
private address/port; you would do that at your firewall. This is
what I do for my personal mail server.
