Another idea is to have the one just use /var/qmail/control/smtproutes to route emails to the other machine internally. But all external email would be hitting that one machine, and also means you're putting all your eggs in one basket, that frontend box goes down you're sol(but if just the internal one goes down at least the frontend will cache).

They allow you to have multiple public IP addresses on the machine, and you can do custom routing: If a connection comes to port 25 on IP 72.168.255.255 forward it to 192.168.1.3 If a connection comes to port 25 on IP 73.169.255.255 forward it to 192.168.1.4 Or however you want to route it. Also provides a good firewall, snort, VPN capabilities, etc. --------------------------------------------------------------------- QmailToaster hosted by: VR Hosted <http://www.vr.org> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- QmailToaster hosted by: VR Hosted <http://www.vr.org> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
