G'day all, Just wanting to check that I've got all the right things to go for setting up postfix on our firewall/gateway.
We have a mail server on the inside of our network, that cannot be reached externally, but serves all mail for our systems. Postfix on our firewall/gateway is to forward all mail destined for our mail systems to this server. To complicate things, we have more than one domain name, but postfix should automagically change the domain name to our regular one on the way through. (Ie. [EMAIL PROTECTED] should be changed to [EMAIL PROTECTED] and passed through to our internal mail server.) Additionally, scripts on the firewall/gateway send to the root user and the root user has a .forward file which contains my email address. I'm not sure what to set mydestination to as according to the docs it "specifies what domains this machine will deliver locally rather than forwarding to another machine". However if postfix is proxying, do I set this as per normal - in which case how should I set it for our other domain names? (Is below correct?) Here's the parameters I think may need to be set in main.cf (got a feeling I've got this wrong as the proxying concepts aren't clear for me): myorigin = $mydomain mydestination = $myhostname localhost.$mydomain $mydomain relaydomains = $mydomain capitalholdingsgroup.com.au mynetworks = 192.168.100.0/24, 27.0.0.0/8" proxy_interfaces = 192.168.100.1 virtual_alias_maps = hash:/etc/postfix/virtual and /etc/postfix/virtual to contain the following line: capitalholdingsgroup.com.au capitalholdings.com.au Any help, tips, pointers, etc appreciated.
