Hi List, I would like to setup a LoadShared Failover internal mail-relay solution (only for sending mail internal->external).
My thoughts: - Setup virtual+physical server in same VLAN (different physical locations) with same OS+Postfix+config - Configure DNS RoundRobin - Have logging from both servers pointing to same NFS-dir and have awstats create statistics from there Internal traffic: - Requests would all be received on RoundRobin_IP, and therefore LoadShared between the servers - Answers would all be send through Server_IP External traffic: - All traffic is done through Server_IP 1. Are the clients ok with answers coming from different IP than send-to ... or how do I prevent this from disrupting client<->server communication - some PostFix/other magic ?) 2. What happens if one of my servers dies. Will RoundRobin still try to send traffic to it, and if so how will clients react on this ? 3. Would Bonding be a better solution for my purpose ? 4. Is there already a RHEL6 howto somewhere, that you can recommend ? 5. What is best practice ? Thanks in advance :-) ! ~maymann
