Hi Jamie, I'll post how I've implemented it here as Taco is a very busy guy, as are all the sun/cobalt team these days. Firstly your DNS records need to be put straight, in the example I give yourdomain.com is the domain we are going to use for etrn and mydomain.com is my servers/hosting that will queue when the other machine isn't online. In dns for yourdomain.com : yourdomain.com Very High priority MX (value of 0) to server.yourdomain.com yourdomain.com high priority (value of 10) to mailserver.mydomain.com server.yourdomain.com IN A 199.199.199.199 So, we've created the primary MX record here pointing to the entry server.yourdomain.com and the secondary MX as the server that will queue mail when server.yourdomain.com is offline. Note that we've created an A record (forward lookup) entry for server.yourdomain.com pointing to the static IP address of the server on yourdomain (the one that is not always connected) Now for the mailserver.mydomain.com configuration. In my case this is a Raq3i, but the principles should be the same on any linux/Cobalt box. I'll presume you already have an account in the Site Management for this domain, if not create one, leaving switched OFF 'accept email for domain'. Now configure the email section on your Raq: Control Panel > Email Server > Parameters In the Relay for the following Hosts/Domains make sure you have the entry in for yourdomain.com and also server.yourdomain.com There should NOT be either of these or www.yourdomain.com in the Host/Domain aliases box (as this will then try to deliver them to the Raq rather than queue them) Save changes, Save changes, and you can now leave your Raq interface. Once DNS propagates then you should have a working setup. Simply set your remote server to ETRN to the IP address of the mailserver.mydomain.com and it should then push the mail down to the box. Pls read the previous post by Taco/myself regarding messages about 4hr delivery timeouts, etc if you want to change them (This needs you to telnet/ssh in) I'll admit this took me a couple of goes to get right, so may be worth doing so in a test environment first to make sure. To check the queue on your Raq, telnet/ssh in and type in mailq And it will show anything waiting in the raq's queue, so you can determine if there is a problem or not. Also tailing the maillog file will show when the ETRN comes in. To do that: tail -f /var/log/maillog And you should see something like: Dec 14 09:28:21 host1 sendmail[5763]: NOQUEUE: Null connection from server.yourdomain.com [199.99.99.99] Which is the ETRN getting through. Good luck! (And if anyone else has any comments, pls post as I'm not saying this is 100% correct or efficient!)
