Hi all I'm looking for a working HOWTO / Tutorial / sample setup of setting up a clustered email server. I know I can setup a CentOS cluster with Heartbeat & drbd, but I'm not 100% convinced it will work for the email as well. Ideally, I'd like to use an open source groupware server, like say open exchange, php groupware, Scalix (free / community version), etc. So, if anyone can please point me in the right direction? I've already setup a heartbeat cluster, and use rsync to sync files for Samba, Apache & NFS, and also setup a Master-Master MySQL replication, but don't yet know how to setup the email server, -- Kind Regards Rudi Ahlers CEO, SoftDux Web: http://www.SoftDux.com Check out my technical blog, http://blog.softdux.com for Linux or other technical stuff, or visit http://www.WebHostingTalk.co.za for Web Hosting stuff

Cyrus-imapd has native replication for example. - KB

It comes with almost all features in exchange except the webmail. We are using it for the last 5 months, and look good so far. It can do load balance and clustering. You can download a 12 user version form www.postpath.com Thanks Rajeev _______________________________________________ CentOS mailing list CentOS at centos.org http://lists.centos.org/mailman/listinfo/centos
