Re: They could hire me
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! |

| 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. |

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. |

1 edit | That could be it too, with the millions of subscribers they have, they would definitely lose some cash getting rid of the many many infected users. Plus the cost of actually finding and removing them.

That is the easy way of solving a problem, but it will cause more problems than it solves. I do not use my isp's mail personally for many facts, I prefer my own mail server as I can customize it, set other rules, and basically be the boss.
Maybe something like by default they block those ports on a per customer bases by default, and you can call in and have them remove those blocks.

In theory that makes perfect sense. In practice, paying for Comcast's Small Biz package does nothing for you. No static IP, can't run a server, I'm still using the same hardware I was on the residential side. All I'm getting for the addition $40/mo is a quicker response time if my circuit goes down.

Hosting a mail server from a residential account is not a legitimate service that is being provided to you on your residential account. You are getting that service by violating the TOS/AUP. Since you are not paying for that service in the first place, you are out nothing if they block it.

keyboard5684... according to RFC standards, relaying mail thru a domain is not permitted. you are only allowed to use the 'local transport agent', i.e. the SMTP server that is located on your domain. i might also add that it is also against RFC to run a public mail system on a dhcp address.
besides... its pretty easy to set up a pop or imap account to download from a remote site, and send out locally.
i work for an isp that does block port 25. we are not huge like comcast, but because of the speeds we offer [9mbps/1mbps] its very easy for a user to pump out a ton of spam VERY quickly [i had the joy of shutting down a spammer on friday  ]. when we did not have port 25 blocked, we had so many spam complaints that we had difficulty getting thru them all in one day. now, with port 25 blocked, we can better tell who is intentionally sending spam, and our workload in regards to spam is much lower. its also alot easier to tell who is intentionally spamming, and who is infected with the latest virus.
another thing that systems really shoud look at doing is checking ALL incoming connections to the mail server. doing this alone makes sure that the mail system contacting you is legit. |

Port 25 is used by BOTH servers AND email clients to send mail to the SMTP server. Such a block would prevent the perfectly legitimate use of using an alternative SMTP server.
