Hi,
By default the PIX inspect smtp on port 25 or even in new versions 7.2 inspect esmtp on the same port , and i as i read it's for traffic coming from higher security interfaces to lower not the opposite . I had a client behind my secure zone trying to use an external smtp, and he use it unless i removed this default inspectioon from the PIX, so why did that happen?
