That sounds almost exactly like my mail config. The only difference is we have one cheap (~$1,000) NAS box that holds the mail store. Every night we rsync the mail files off to a backup NAS. It's not entirely a single point of failure--but it'd be a pain if the NAS quit. At some point we'll setup something like DRBD to keep them in sync. Probably right after a NAS failure... ;) -A
