Without knowing exactly how the > mail is being submitted there's no way to know whether that would work. The mail is being submitted by 'smartd', the smartmontools daemon... according to the docs, they use 'mail' (don't know why). Since smartd runs (at least starts) as root, I guess the message *is* being submitted from root. Does that clarify anything? Thanks, Jay
