| [E-mail] Microsoft Hotmail Blocks Comcast Traffic Microsoft Hotmail Blocks Comcast Traffic
For several days now - Hotmail traffic sent by Comcast users have been blocked. Some claim this is a blacklist gone awry, others claim that its Microsoft's attempt at attacking a large spam distributor, and others misconfigurations. Comcast has no official word - but many people are getting errors reporting that "denied permit" - what this exactly means is unclean - but most likely that Hotmail is denying Comcast permission to send their users emails.

| Re: [E-mail] Microsoft Hotmail Blocks Comcast Traffic Thanks very much for posting this. I have an email list of around 70-80 people and last night I started getting this "550 Permit Denied" message. Thought I had done something wrong but it looks like a Comcast vs. Hotmail, etc. issue. Hopefully, they will get it resolved soon. | |

| Re: [E-mail] Microsoft Hotmail Blocks Comcast Traf We've been having the same problem between Comcast & Hotmail all day. It will be interesting to find out what's going on...
Thanks for this forum, otherwise I'd have spent way too much time trying to figure out what I was doing wrong | |

If true, it's hardly surprising, since they are also ranked in the top 3 ISPs in terms of number of users. That is a lame excuse. Comcast is No.1 in HSI customers, No.3 in spam abuse; SBC is No.2 in HSI customers, No.1 in spam abuse. Right from the gitgo you can see that there is no correlation between size of customer base and spam. There are are 61 entries for Comcast in the Spamhaus list, 91 entries for SBC in the Spamhaus list. Let us break them down:
Comcast SBC
-----------------------------------------------------------------------
Proxified
Residential 25+ 5
Customer
-----------------------------------------------------------------------
ROKSO 17 32
Other 18 54
-----------------------------------------------------------------------
Non Resident Total 35 86
-----------------------------------------------------------------------
Residential Total 25+ 5
-----------------------------------------------------------------------
Grand Total 61 91
HSI provider No.1 Comcast - 7,705,000 subscribers
HSI provider No.2 SBC - 5,968,000 subscribers
»www.leichtmanresearch.com/press/···ase.html
...and here is more subscriber data:
»isp-planet.com/research/rankings···005.html
Now let's do some math. Ratio of ROKSO spammers to total spammers:
Comcast: 17:61, or ~28%
SBC: 32:91, or ~35%
Comcast: 35:61, or ~57.3%
SBC: 86:91, or ~94.55%
Ratio of, presumably (the figures don't detail, but the Spamhau list of assigned IP addresses seems to support) mostly residential customers to total spammers:
Comcast: 26+:61, or ~42.6%+
SBC: 5:91, or 5.5%
One more comparison is in order:
The ratio of Comcast HSI customers to SBC HSI customers: 1.28:1
The ratio of Comcast HSI spam spewing customers to SBC HSI spam spewing customers: 5:1
Any way that you look at it, based on HSI customers, Comcast, which doesn't block outbound port 25, is way ahead of SBC, which does block outbound port 25, when it comes to open proxy spam from infested residential customer computers. So stop blowing smoke about how Comcast leads in spam abuse because they lead in customer base.

Comcast does block port 25 for compromised systems. It's whack-a-mole, to be sure, but it works without punishing customers who run AV, keep their systems patched, don't download crap, and usually run with minimum system privileges.

I don't like that I get so damned many connection attempts from unblocked Comcast customers to my MX server. If I didn't have friends on Comcast I'd just block them at the firewall.
You don't need port 25 to use outside servers. I use outside servers that listen on port 465, or on port 587. Port 25 was never intended for email message submission; and the sooner we stop mis-using it, the sooner the spammers won't be able to abuse it.
You gotta be kidding, right? Comcast port 25 blocks are completely ineffective. They go in place for 48 hours, then they are lifted. If the blocked customer actually uses a mail client, they might notice; but I know a lot of people who don't even know what a mail client is. Those who rely entirely on the Comcast web mail service will never know when they get blocked, and, thus, never know that they need to clean their infected systems. Idiots.
said by scooby :Norman you are forgetting T1 customers. SBC has a huge lead in the number of business customers and those get infected as well. Then why aren't they showing up in the Spamhaus stats? Why aren't they showing up in my mail logs. Both the Spamhaus stats, and my mail logs tell me that you are wrong.
said by scooby : reply to mbnva Re: [E-mail] Microsoft Hotmail Blocks Comcast Traffic I dont get the argument on size/spam rank. Maybe more spammers are chsi cust. But the more cust you have, the higher chances for more spammers. You didn't even look at the numbers. There is no correlation to how many customers you have and how much spam you send.
Comcast only has 1.3 times as many customers as SBC. Comcast has 5 times as many compromised customers, with spamming Trojans, as SBC has.
And you haven't seen the end of the spam blocks. Yet.

| Maybe i am not following this correctly, but you say that Comcast has 5 times as many compromised customers as SBC, but that isn't true. They have 5 times as many compromised RESIDENTIAL customers as SBC. If you include non-residential, SBC has 1.5 times as many compromised customers (overall) as comcast.

Is this correct, or am I misunderstanding something, the thread isn't just about residential customers but customers as a whole? I don't even know where you are getting that "1.5 times as many compromised customers". SBC has a large number of commercial spammers who actually pay SBC for connectivity for spamming. Those costumers are not "compromised", they are paying SBC for the privilege of spamming. They comprise roughly 95% of the total spamming reported by Spamhaus as coming from SBC IP addresses. These guys are actually running MTAs on their IP addresses. SBC abuse doesn't do squat about them because they pay enough money that SBC sees them as a revenue stream. You wouldn't want to kill the goose laying the golden eggs, would you? Well, neither does SBC. (Not that I agree with that position; if I were paying the HSI bill here, and not the landlady, I would switch to DSL Extreme, or Speakeasy, in a heartbeat! And tell SBC why I am leaving when I leave. Alas...And I have spent too much time bitching in the SBC private NNTP groups; I have a reputation there, but it isn't the best.)
The "compromised" customers are mostly residential customers; the ones who get the spamming Trojans installed on their computers. About 95% of them would never miss port 25 if it was blocked. The latest crop of them are probably like my Comcast sister, or SBC Yahoo! DSL Service cousin; the former doesn't use an email client, preferring to use the Comcast Web email interface, the latter was happy not to lose his Yahoo! Mail Web access. Neither would ever notice a port 25 block. These make up the bulk of the proxy spam. Comcast has only ~1.3 times as many of these customers, yet ~5 times as many of these customers are spewing spam from the Comcast network.
said by funchords :But what do you mean about port 25 never being intended for email submission? That's been the port since I've been on the net ... more than 10 years now. »www.faqs.org/rfcs/rfc2821.html
This describes the "Simple Mail Transfer Protocol". Mail transfer, as in forwarding email from MTA to MTA until the destination. Unless you are running an MTA, you don't need port 25. The fact that port 25 has been used for message submission up until now doesn't mean that port 25 was always intended for messages submission.
»www.faqs.org/rfcs/rfc2476.html
Dated December, 1998, so it goes back a ways. This describes "Message Submission", as in injecting email into the SMTP session. It has been around long enough that mail administrators should be aware of it. Any mail administrator who refuses to implement RFC 2476 is being a "stubborn ass". It isn't hard to do. It is just, well, not "traditional". Not more than ten years old, to be sure; but not invented yesterday, either. Somebody foresaw the need for authenticated message submission seven years ago; just about two years after the first inkling of trouble with spam. If every email provider used authenticated message submission on port 587, as described in RFC 2476, then proxy spam would be as much a thing of the past as relay spam is now.
As for a provider refusing to implement an RFC; I would recommend them to "RFC Ignorant", for a listing!
»www.rfc-ignorant.org/
And look elsewhere for email service.

Reverse DNS for 63.240.77.81
Generated by www.DNSstuff.com
Location: United States [City: San Diego, California]
Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 63.240.77.81 is found by looking up the PTR record for
81.77.240.63.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us know what to do next.

Globat (my domain host) is behind the 8-ball with their port-25 only SMTP configuration. And I really wouldn't mind if Comcast blocked port 25 by default but allowed users to lift the block permanently, for free, via a webform or tech support call.I think that would solve 90% of the problem and I would be just as satisfied. Well, that does happen to be the way that SBC handles it. But I would not say "permanently"; rather, for as long as no abuse is propagated from that account. I am also "soft" on my position; I did not request a lift on my port 25 block while the only off-network SMTP servers I was using were accepting messages on either port 587 (GMail, GMX Mail), or port 465 (MyRealBox). When I found that Yahoo! Japan (smtp.mail.yahoo.co.jp) was port 25 only, then I requested the unblock. | |

No way around it. When a mail server denies access, you have to find out why. That is between Comcast and MSN Hotmail administrators. Comcast does hae a problem with one of their output servers; it isn't configured properly. Though it won't always result in rejection (my server is ok with it), some administrators won't talk with an output server which doesn't have a DNS lookup matching its HELO.

Figure 1. |
said by MarkinFL :
I have been having the same problem for over a month and half. I am getting upset. I can't get email to business clients that have @hotmail.com. Then of course there is the NOT RELIABLE @AOL.com they don't even let you know they did not handle it...the sender or receiver knows nothing AOL simply deletes it in cyberspace... I have been using email since we had a Microsoft mail server. The last 3 years have been the worst...its getting to the point I have to call and verify if clients receive. This is crazy.
This is the result of defensive measures being taken against spam. If we would just have accepted spam, without trying to do more than just delete it, the spammers wouldn't be taking all the measures that they do to defeat filters, and blocks.
AOL is interesting. They do have a response when I try to run an SMTP verify with Sam Spade:
11/30/05 09:47:06 SMTP Verify %User_ID%@aol.invalid, at mailin-04.mx.aol.com
Contacting 64.12.138.89
554- (RTR:BB) http://postmaster.info.aol.com/errors/554rtrbb.html
HELO aosake.net
554- AOL does not accept e-mail transactions from dynamic or residential
554- IP addresses.
554 Connecting IP: 71.131.210.202
Doesn't want to talk to us
That isn't testing a regular ISP SMTP server, though. I have already demonstrated an issue with the Comcast output server, "sccrmhc11.comcast.net (63.240.77.81)", which won't answer to a DNS lookup with its name. Comcast needs to address that issue.

| I'm getting the same problem all today:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'namedeleted@hotmail.com'. Subject 'Answers', Account: 'mail.comcast.net', Server: 'smtp.comcast.net', Protocol: SMTP, Server Response: '550 permit denied', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
But I didn't have the problem with the same address just yesterday. Thanks to this forum I can see the ball is in Comcast's court...heaven help us. | |

@comcast.net | It has to do something with Comcast. I send the same email from my Earthlink and my Work exchange email, those both make it to my hotmail fine. When I use my comcast account it is immediatley rejected! | |

@comcast.net
| I just went to Comcast's home page and did the interactive agent. It says they have suspended any activity for 48 hours to msn or hotmail. it says if you are getting the error your computer may be being used to send spammers emails without you knowing. also if you have sent a lot of legitimate emails, you should email; mymessageisnotspam@comcast.net and tell them you are sendign legitimate emails. Also, your email address and how many people you are sending legitimate emails too.
All the time this will take, I think comcast will be crediting me for 48 hours of my bill!!! | |

| Sorry to throw a bone in here, but it doesn't seem to be Hotmail, rather Comcast.
Recently, mail sent from Comcast's mail servers to my personal dedicated server for multiple domains comes back instantly, saying the server cannot be found, while Hotmail, Gmail, Yahoo and other services and servers work without issue.
So, having said that, I believe Comcast is having issues. | |

@comcast.net | And it's happening again now currently because of the recent outbreak of the Sober virus.
Let's hope the SOBs figure it out soon and work so each others email go through. | |

Albuquerque, NM | I received this information from Comcast: The issue is with Microsoft and a sober virus, Microsoft, hotmail, Msn and Comcast are working together to get this fixed. (A sober virus is like a trojan worm.) You should be able to send email shortly. | |
