They could hire me

I need a job, I could do it.

I hope they go about it the right way, instead of limiting service by blocking port 25, etc. I'll switch to Verizon if that happens.

They need to block 25. No reason you can't use thier smtp servers.

I think that is a bad idea. By ISPs blocking port 25 they cannot connect to other servers (like there domain hosting company) to send legitimate email. By doing this others create a work around, you can use a different port. After a while the non-standard port becomes standard. Then ISPs begin blocking other ports.

P2P has the majority of users doing illegal stuff (I know, some of it is legal but most is not). Does this mean ISPs should block those services too?

What about VOIP? Using VOIP services from other companies means a loss in profits for the ISP if they offer VOIP. Block that too?

IRC generates a ton of non-legitimate "chatter".

You get my point. ISPs should not block ports, they should terminate users that break the rules.

How do you use non-standard ports for email? Other servers won't look at 28 or something.

People forget it's a residential service and not a business one. If you want to send email, use smtp.comcast.net. Otherwise, block it. I'm sick of putting in cable modem users in my spam list. The few/stupid ruin it for the many. A shame, but life goes on.

Well, at this point it couldn't hurt to try SOMETHING, because so far it seems Comcast thinks it will just go away on it's own.

Other servers won't, but a hosting company can set their servers so that they accept mail on port 28 from their customers. It's a very simple thing to do, and I'd do it for my customers in a second if anyone needed it.

Bullshit! Many people use their internet connections for things other than just surfing web pages and email friends and family. Once ISPs start blocking ports to protect/correct the stoopid (not the cable modem users,) the rest of us lose!

Rules, rules, and yet more rules won't make anything any better. It will make it stoopider!

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 you need to run a server or have business needs you should use the business end otherwise you use the residential version. If you are running a server on a residential line be careful. A lot of ISPs consider that a TOS violation and could cancel your service. Cox blocked port 25 and it made people mad. I am glad they did it though. A lot of people who were complaining about not being able to do business and stuff with port 25 blocked were on residential lines and they were forced either to cancel service or get the business service. Either way it cut down the crap on residential lines.

Most/Many SMTP Servers monitor not only Port25 (The MTA [Mail Transmission Agent] Port for Server-to-Server forwarding of Email) but Port587 (The MSA [Mail Submission Agent] Port that is SUPPOSED to be used to submit Email into the System instead of Port25). If an ISP REQUIRES the use of Port587 (along with SMTP AUTH as Required by the Port587 RFC) for all To-Be-Relayed mail submission to their Servers (no matter if it comes from their LAN or the Internet WAN) then they solve the issue of Trojan Spam Code pumping SPAM through their system.

Amen to that. Removing legitimate services from all users to keep a few users from "going bad" is a rotten strategy.

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.

There are two very good reasons not to use Crapcast' smtp servers
1) they are down most of the time
2) thewy lose mail even when they are up.

I have a reason, I have my own domain email address and I use to use Comcasts smtp servers for my domain email until some isps blocked Comcasts smtp servers for "spam complaints". One example is, about every two months, when I tried to send email to my grandparents on webtv, the email would bounce back with "spam complaints." Then I would have to contact Comcast and eventually (after they stopped playing the blame game) get them to contact webtv to get off the spam list. After a month or two later I could send email to webtv again. Then two months later, the same "spam complaint" problems started again.

If I still used Comcast smtp servers, over half of my friends and family wouldn't be able to receive any of my emails. Now I use my domains smtp server which lets me send up to 50 emails a day for free. The most emails I send in an average day is about 10 or less.

Blocking ports to stop infected boxes from sending spam is like putting a bandaid on an infected sore - it masks the symptom but doesn't solve the problem.

Comcast has crappy email servers, and we'd be forced to use them if they block 25. What would be next, blocking 53 so we can only use their crappy DNS servers? Only allow port 80 to comcast.net? We don't need access to the rest of the web. Think about it.

As I said, I would switch to DSL in a heartbeat if they ever pull this sort of crap.

The more I think about it, it seems they aren't even hoping it goes away, they just don't care about the spam problem.

Could be they don't want to lose the revenue stream they get from the spammers on their network.
