Hi, My setup is 2 x Ubuntu 9.10 (x64) servers with ISPConfig 3 installed as per the very clear how-to posted by Falko: serverA.mydomain1.tld serverB.mydomain2.tld I have never run a mail server successfully before and I need help with configuration. I have a static IP. 1. My ISP allows two methods of routing mail - the information is here: http://www.internode.on.net/support/guides/email/secure_email/. They also are willing to help if I decide to run my own system but I'd rather use their service. Can someone please help me with how to configure serverB.mydomain2.tld to use this service. For example - how do I configure postfix .. 2. I want to direct all mails from serverA.mydomain1.tld to serverB.mydomain2.tld internally (behind my router) and I wish to send out (to the WAN) and receive mails (from the WAN) on serverB.mydomain2.tld only. Will this be possible? 3. When setting up a DNS zone in ISPConfig 3 I notice that the control panel very handily sets up a number of "records" by default. Are there any more records I need to set up for mail boxes? I hope my questions are clear. All help much appreciated.
