Large attachemnts. The IPS's are way behind the times on file size and limits. Other than that you are corrrect  |

the port 25 blocking is for all bellsouth customers but the ones interested in upgrading their services to business
it is only a money broblem hidden behind a security BS.

Its too bad the money to be made off of stupid users who refuse to secure their machines is more important to BellSouth than the responsible users who do secure their machines.
I don't see Comcast making any improvements to help lower the number of spammers on their network -- making them the #1 ISP with the most spam users.
I don't think that is totally correct.
According to my router logs, I get more spam and zombie attacks from a few other DSL and cable providers. Comcast IPs rank in the middle on my router attacks. The most, believe it or not, is Charter and SBC.
Well, lemme look at my (SMTP) logs. From the last four days:
Relay access denied (total: 273960)
14187 comcast.net
6137 shawcable.net
4942 attbi.com
3881 greatosee.com
3126 rr.com
blocked using dynablock.njabl.org (total: 263297)
46633 comcast.net
12876 optonline.net
12746 rr.com
10236 attbi.com
9189 ameritech.net
Not only is Comcast the biggest offender in two block categories, they are the biggest by a considerable margin. Comcast seriously needs to do something about their networks.

But at least Comcast isn't blocking port 25 (yet). I don't see why I should have my network connection hobbled because of idiots who refuse to secure their machines. I would fully support any ISP that yanks connectivity from lusers who refuse to use firewalls and/or patch their operating systems.
Which IS the problem! Until Comcast blocks port 25 to keep 'certain' customers from using Comcast SMTP servers for inappropriate activities, the problem will continue. |

Mindspring was blocking port 25 back in 1996 when I worked for them. This is not new at all. There shouldn't be a legit reason to be sending mail using your ISP's dmain mail server while not using your ISP's domain.
And the problem isn't as simple as stupid users not securing their accounts/computers, but that Spammers signup for accounts and then use accounts elsewhere to relay through the unfortunate ISP's SMTP. This is an old trick that no mature ISP would allow the convenience of port 25 being open in the first place. |

Cox in Virginia is blocking it too. I remember things breaking on me. Not only did I have outlook problems, my scripts for the linux servers stopped working. Usually, I have the server email me via a script when it is done doing something, like rsyncing. I wasn't too happy about it. After debugging, I went to the website and searched what they did. Pure B.S.
After this protection against spamming, has it worked? I steadily get more and more spam myself. |

Not the same, and not really any re-programming.
It has now become standard for many ISPs that provide hosting to provide an alternative port for outbound mail. This is because of the port 25 blocks implemented by ISPs.
Blocking ports is not the way to go, for anything. Even the sasser worm, most ISPs blocked certain ports to prevent the spread. The true answer is to patch machines or cut off there service. Sooner or later those same users will be the ones to cause trouble else where. Leave them open and deal with the users. Send warnings and take action. |

One reason I have SpeakEasy as my ISP is because they don't block ports nor have limitations against servers. If SE blocked port 25, killing my email server, I would look elsewhere. I don't think SE will do that, however, as such an open ToS is part of its attractiveness.
I would call SpeakEasy a fairly major ISP these days.
BUT I do agree that methods should be made to enable blocking ports on a per-subscriber basis. If I neglect my updates and security, I would have no problem with SE blocking port 25 for a few months if I were found to be a spam relay. In fact, I'd encourage it.
Keeping one's address book as a separate text file is a bit extreme. Myself, I use Mozilla for email and web browsing. So far, haven't had anything infect my machine, much less access and use my address book.
But I guess for some using Mozilla is just as extreme as keeping their address book as a separate text file

Port 25 is the MTA to MTA standard. However, RFC 2476, § 3.1 specifies port 587 as a standardized port for ESMTP based message submission.

I agree. But maybe if they started blocking port 25 the number of spam messages would go down.
BellSouth isn't blocking all users, only new users and those who upgrade.
Since BellSouth DSL is using PPPOE, and each customer has a "profile", I think it should be on a per customer basis. If a customer is found spamming, their account should get their port 25 blocked and after 6months to 1 year, have the block removed.
If all ISPS continue to block 25, then port 26 will become the new "stanard" port.
All customers are getting port 25 blocked, it doesnt matter if you are new or old, and there is no getting the block off, it is clearly for spamming and security issues, customers cant get a "business" account and get the port unblocked, it doesnt work that way, if you arent blocked yet then look for it coming, all major ISPs are headed in this direction.....and Im glad......im tired of all the people whining about spam and dont know why they get it. Keep your computer CLEAN and quit giving your address to every website and/or person you meet. Keep you address book in a text file so IF you get infected it cant use it. Get educated on what is out there and what you can get just by going to the wrong site or giving the wrong person/website your email address. |

I don't think that we will have to worry about something such as 'port 26' becoming a standard. This would require all email servers and programs to be rewritten, and implemented. That would be the equivalent of stating that web pages will now run on port 81 instead of 80, and electricity will now run at 50Hz, 220V instead on 60Hz 110V. |

Your ISP may already be "blocking" port 80 and you won't know it. Several ISPs do transparent proxying of web traffic. All traffic gets forwarded through HTTP caching systems. They do it to help eliminate redundant traffic from their networks and improve the overal browsing experience by speeding things up (at least static content).

My ISP has that as an optional service meant to benefit dialup users (speed up downloading graphics, etc). All you do is just point your browser to their proxy. Didn't really help with DSL.... |

Rob,
sooner or later they will be blocking all users. They started with the Dial-up accts and are slowly migrating to DSl. I had my port 25 block about 2 months before getting the new Extreme package. Eventually everybody will be blocked

The only people that have need of port 25 outbound are ones who are running their own SMTP servers. The vast majority of providers prohibit the running of servers by their residential service consumers. So, to these providers, if their actions negatively impact your ability to violate your ToS agreement, it's only going to be viewed as a win.
For those of you that cry about this impacting your ability to use an SMTP hosting company's services (or even your employer's SMTP hosts) for relaying, that's a matter of implementation. Your SMTP service provider should be providing SMTP client service via an alternate port, any way. If they can't figure out how to do this, they really shouldn't be operating SMTP servers in the first place.

That's probably because you are on SBC and the attacks tend to come from sources closer to you (i.e. fewer hops)
