Usually the hardware would make sure that stuff doesn't disappear (UPS, powered RAM, harddisk condenser) and not some weird software workaround that complicates and slows down everything. The only possibility one could still lose mail when having proper hardware failsafes would be if the kernel had a bug and crashed (and that's so bad, it doesn't really warrant any working around it). But maybe that's just me. cheers, Danny
