Re: [E-mail] Microsoft Hotmail Blocks Comcast Traf
This issue has not been resolved. I still cannot send to a hotmail account without getting that error message.

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.

One workaround: use gmail to send mail only
said by howardthebrit :
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.
Actually, the ball is in hotmail's / msn's court. The receiving smtp server has the overzealous rule.
As a work around, I can send all my mail through my gmail.com account.
You need to have a working gmail account, and you need to edit its settings to allow pop3 access (even though you're not going to access it.)
Edit your existing Comcast account profile in your pop3 client (such as Outlook). Change the outgoing e-mail server to smtp.gmail.com port 465 (Outlook users will need the advanced tab to set the port). Enable that your outgoing server requires Authentication and enter your gmail username and password there.
From that point on, your incoming mail still comes from Comcast, but your outgoing mail goes through Gmail.

T 20051130 002239 438c26b3 Connection from 63.245.72.124
T 20051130 002241 438c26b3 HELO 71.131.210.202

T 20051130 002244 438c26b3 Connection closed with 63.245.72.124, 5 sec. elapsed.
Some MX servers go an extra step, and run a DNS lookup on the IP address. Had I done so, I would have seen:
11/30/05 11:56:51 dns 63.245.72.124
nslookup 63.245.72.124

nslookup 200.164.81.246
No reverse DNS (WSANO_DATA)
Now, review my post concerning the Comcast SMTP output server, "sccrmhc11.comcast.net (63.240.77.81)". There is no rDNS for that IP address. Since a fair percentage of spam originates from such IP addresses, and there is no way to verify that the machine saying "HELO sccrmhc11.comcast.net" is even a Comcast mail server, MSN Hotmail is within their rights to refuse connections from that machine.
For the record, Sam Spade says this about that IP address:
11/30/05 12:15:53 dns 63.240.77.81
nslookup 63.240.77.81
Canonical name: sccrmhc11.comcast.net
Addresses:
63.240.77.81
Anyway, my point is this: Given the nature of spam source IP addresses, mail administrators of MX servers are within their rights to refuse connections from IP addresses when they can't verify that the connecting machine is who it claims to be. You may think that is being overzealous, but you can fix your SMTP output server so it doesn't fail against such tests.
AOL refuses connections from SMTP output servers on residential dynamic IP addresses. I can't relay mail from my computer to an AOL MX server through my MTA. I fix that by relaying through my ISP's MTA. My SMTP output server goes through an SBC authenticating SMTP server. Oh, BTW; that is within the SBC Yahoo! AUP/TOS.

I think the issue isn't that Comcast is blocking port 25, rather, that MSN Hotmail is refusing connection from some Comcast SMTP output servers. That is a matter for Comcast and MSN mail administrators to hash out.

It appears that Comcast has finally addressed that problem.
I had forgotten that port 25 blocking had popped up as a side issue; and I even posted my thoughts on that matter.

Well you have me convinced about the misconfigured server, but there must be something else as well, because I still have the problem.
This is the official response from Comcast:
Thank you for your message concerning your Comcast e-mail service, my name is Susanne.
Emails sent from Comcast.net subscribers to MSN or Hotmail.com email accounts will be denied and the subscriber will receive the error "550 permit denied". This is caused by a problem on Microsoft's end caused by a virus. Microsoft is actively working to correct the issue. No ETC was supplied.
To assure the proper tracking of this issue, we have created the following customer service ticket: xxxxx
Please refer to this number should you contact us regarding this same issue.
Thank you for choosing Comcast.
So there we have it - "Not me sir, its a virus that's attacking them" |

Re: [E-mail] Microsoft Hotmail Blocks Comcast Traffic
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. |

You're not the only one. If you've ever tried an SMTP session in Telnet, you'll see that Comcast's servers sometimes take 30-45 seconds to respond to the previous command. Sometimes, it is fine.
You can set your server timeout to up to two minutes with no downside. There should be a setting for this in Outlook Express.

Tested: This is COMCAST's problem
I ran a telnet session and was able to confirm that this is comcast's problem. This is not a bounce from hotmail -- hotmail is not even being contacted!
Here's how to try it (you input the part in bold):
c:\>telnet smtp.comcast.net smtp
220 comcast.net - Maillennium ESMTP/MULTIBOX sccrmhc12 #110
HELO comcast.net
250 comcast.net
MAIL FROM:<yourname@comcast.net>
250 ok
RCPT TO:<yourfriend@hotmail.com>
550 permit denied
quit
221 comcast.net

Hmmm. I guess that there are two problems. The post which got this thread started wasn't clear on the source of the error, but a later post offered this:
Reporting-MTA: dns; comcast.net

Last-Attempt-Date: Wed, 19 Oct 2005 17:48:21 -0000
That is clearly a Comcast server with no rDNS configured. I was able to prove that earlier by using Sam Spade to check the rDNS name on a Comcast output SMTP server, and there was no rDNS reported. About two hours later, there was an rDNS name on that server.
So, just now, I did a rare thing. I don't do this often because it is an abuse of my niece's trust; but I had to see just what was happening. I fired up MS Outlook Express (because it is easiest to change server configuration on the fly), and plugged in her Comcast account information. My first attempt to send an email to one of my MSN Hotmail accounts failed:
The message could not be sent because one of the recipients was rejected by the server.
The rejected e-mail address was '%User1_ID%@hotmail.invalid'.
Subject 'Server test.',
Account: 'SMTP Test',
Server: 'smtp.comcast.net',
Protocol: SMTP,
Server Response: '550 permit denied',
Port: 465,
Secure(SSL): Yes,
Server Error: 550,
Error Number: 0x800CCC79
I still had the message in my outbox, so I opened it up to edit the recipient list. I changed the Hotmail account, and added a non Hotmail account, then resent the message. The second attempt went through. I can't seem to find the Hotmail Beta configuration to get at the full headers, though. So all I can get from the Hotmail account is this:
Proper Name (%User_ID%@gmail.invalid)
To: "Proper Name" <%User2_ID%@hotmail.invalid>
Cc: %User2_ID%@netscape.invalid
Subject: Server test.
This is just the latest Comcast SMTP server test.

P.S. No Comcast email address was needed for this, due to the nature of the Comcast servers. I want to stress, for the sake of my niece, and her parents, to the Comcast staff who may see this, that I do not use the Comcast servers; I only did this specifically to try and see what is going on. For my regular email smtpauth.sbcglobal.net is good enough; or I can use a couple of other SMTP servers where I have authorization as a user. Except for the occasional problem with AOL blocking it; so you Comcast folk are not alone in these ISP pissing matches over SMTP servers being blocked!
