I just re-read his message. I don't believe he's actually talking about AV/AS addons for post Postfix. I think he's talking about "complete" commercial edge solutions, ala Astaro, Barracuda, IronPort, et al. "Some commercial email platforms...far outscale Postfix" Michael Katz is a commercial vendor, so it makes sense that he'd want to sell you a completely new "solution", not a paltry commercial AV addon for a FOSS mailer. -- Stan
