If you just want some hot standby setup (no load balancing while both servers are up), and if you are going to run it on Linux, I would recommend using a setup with heartbeat (for the failover) and DRBD (for replication of the block device used for storage). I have been using such a setup for almost three years now (in two different sized setups) and it never failed on me (except for two occasions on which I managed to kill both servers at once - totally my fault). Unless you want to use the most recent cyrus-imapd beta (2.3.1) which has some cluster support built in. cu, sven ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
