Most applications should work with the Heartbeat + DRBD combination for a failover setup with redundant data (think RAID 1 over the network). Although I haven't implemented a highly available email server setup, I have worked on highly available PostgreSQL and NFS servers. The only downside to using Heartbeat + DRBD is that one node will be completely idle, while the other one will be handling all of the load. Application-level mirroring/clustering allows you to load balance and leverage your hardware better. You may want to explore the clustering capabilities of IMAP/POP3 servers like Courier and Cyrus. --> Jijo -- Federico Sevilla III : jijo.free.net.ph : When we speak of free software GNU/Linux Specialist : GnuPG 0x93B746BE : we refer to freedom, not price. _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
