-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm not changing my stance, I see where everyone is coming from. I know however that mail servers can create alot of unwanted traffic on a network. Especially a large WAN like cableones. I think most of us on the list would agree that technology is a very dangerous thing in the hands of 85% of the world. People just get a piece of technology and turn it on. If it works, then hey great. Example 99.5% of the wireless access points in Sioux City. Someone goes to Staples and buys a wireless router, takes it home and turns it on. They fire up a laptop or computer and it works right out of the box. You know every Linksys and Belkin manual in town is sealed up nicely in its packaging because NOBODY reads the manual. It's the same thing with people who don't configure their MS Exchange boxes. Working at an ISP, I can tell you that daily we deal with at least 25 to 30 messages about spam coming from an IP range in our network. This in turn eats up anywhere from 2-5 hours of admin time. By the time you research who it is and find out what is on their network, try and relay a message through them, contact them, explain what is going on to them, then responding to the report. And we are only in a handful of small communities. Using the tools available now, I'm sure cableone has graphed their traffic by port flows and see that activity on incoming port 25 is way higher than it should be for a mostly "residential" cable plant. As an ISP we've never thought about turning off certain ports but instead limiting the flow of that traffic with shapers. We have customers that we sell bandwidth to that actively filter out file sharing. Why, because it's their network and they can't afford to get more bandwidth. So what do they do??? They sample the traffic and limit what ever puts the most strain on their pipe. Also to say cableone isn't concerned with upload bandwidth? If they weren't concerned do you think you'd be limited to 256K uploads?
