I thought about separating my mail and web server for performance and security reasons. Server1 should only serve webpages, server2 only email. Both should be administered in the same ispconfig 3 instance. My idea was to not actually mirror the servers but in order to be able to save space keep web documents only on the 1st and email only on the second. I have followed the recent tutorial about clustering ( http://www.howtoforge.com/installin...tabase-cluster-on-debian-5.0-with-ispconfig-3 ) and skipped the steps with GlusterFS. The database is replicating but obviously I cannot create a mailbox on server 2 from the ispconfig panel on server 1. Is there a way of achieving this or am I on the wrong track? Both machines will be hosted as vm's (on the same machine) and I'm using lvm volumes for /var/www and /var/vmail respectively. Could this help in any way?
