See, that's the thing. I haven't done any playing with cisco routers, but I would imagine that the ios is smart enough to drop anything except an email packet at port 25 and then with all the recent problems with ddos attacks and virii, etc, I would think that they *would* want to seriously filter the headers that come in. But you guys are saying that the headers on my email - no matter which machine I'm sending from - are absolutely normal? Nobody would or could do it differently?
