One question is whether your uptime definition means "someone can connect via IMAP" or "someone can connect via IMAP and IMAP acknowledgements of state-changing operations are guaranteed to be replicated across the cluster". If you actually want your cluster's semantics to preserve email client operations in the face of the loss of one member of the cluster then rsync is not enough. > What other solution would you think of ? You might want to chase down the Cambridge patches to cyrus, which added an application-level transaction log to that particular imap server. -- jan grant, ISYS, University of Bristol. http://www.bris.ac.uk/ Tel +44 (0)117 3317661 http://ioctl.org/jan/ Leverage that synergy!
