Re: They could hire me
They will lose a % of customers that need to send mail via there jobs e-mail server.
What they need to do is stop selling modems, but sale routers with these ports filtered and have directions on how to unblock.
Any user smart enough to unblock a router should be reasonably responsible. |

| If they do resort to blocking port 25, they should offer a "power users" or "home office" service tier with the port unblocked, and/or email servers allowed, maybe for a little more $ per month. The extra $ could go into monitoring power users to make sure they don't get infected and spew spam, and shut them down if they do.
Although one "can" use smtp.comcast.net for all their mail, there may be reasons one cannot - say because they're working from home or taking online classes and are required to use another server. Or becuase the address they're trying to send to blacklisted comcast's IP range. Also, Comcast's email servers aren't particularly well administered. They tend to block anything that "could" be the virus of the week, for example, try sending an email with an attachment named update.zip, regardless of content, to a comcast.net address. It won't arrive, and no notification that it wasn't sent. |

Rather than blocking ports at the server, ISP-supplied modems could be equipped with routers that block most "advanced" services by default.
For some reason, cable modems usually don't come with a NAT router or any kind of firewall/port filtering. ADSL modems often do, and it's not only a good security feature, it makes it easy to set up a nice little SOHO LAN.
They usually ship with all ports open by default, but they are quite easy to OEM with custom settings from the ISP. |
