BrightMail is probably one of the best commercial solutions currently available. Cerient is the place I'd go if I didn't want to implement the FOSS way myself. Go Cerient! Anyway, I looked at many and BrightMail stood out. MY biggest obstacle was hardware for the SMTP Gateway... but I still like the accountability factor. It's not that Symantec will blink if I threaten to leave them, but if something *does* go wrong - CEO's anger gets projected at THEM and not ME!! :)
