I have Edge Server in Cisco PIX 515e (Pix OS v 7.x) DMZ network, and Hub Transport Server INSIDE. When esmtp inspect enabled on PIX, TLS connections works incorrectly, because esmtp inspect strips out any non-esmtp commands. Disabling esmtp inspect maybe a solution, but this is opens to everyone, who is OUTSIDE, server banner, commands supported, etc – and in my opinion this is no good because of less security. Will you recommend to leave all things as is, or maybe possible change of Hub-Edge Servers authorization methods? Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
