OK...I'm searching for strategies to have a "realtime" email backup in the event of backend failure. We've been running cyrus-imap for about a year and a half with incredible success. Our failures have all been due to using junky storage. One idea is to have a continuous rsync of the cyrus /var/spool/imap and /var/lib/imap to another server I've also considered delivering email to two discreet email backends and keeping the /var/lib/imap file sync'd . I don't think I can use murder to do this. Is anyone out there using RHEL in a cluster that would like to share their architecture? Any contractors out there that want to get paid to help us implement?
