SBC, Bellsouth, and some others who block port 25 outbound aren't even on this zombie list maintainer's radar.

Verizon, the 4th largest HSI provider appears to be No.2, after Comcast.

I'm not saying that it's not effective in solving the problem.

Taking away cars is a great way to eliminate car crashes.

I am not talking about banning cars, I am talking about banning Pintos. There is always port 587.

To be fair, I'm not 100% strong in my support of my own position here.

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.

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

Comcast v. Hotmail 550 permit denied issue continues. Comcast has had terrible DNS problems getting worse rather than better for the past 5 months. Now I can't send business email to my correspondents. I forget - I'm paying $150 per month for what?????? I'm headed back to Verizon. I don't NEED 6 mbps for email, just reliable DNS and smtp!

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

It does not continue. It is happening again. The issue is with microsoft, not comcast. It was due to some type of virus which I heard from a microsoft rep. So go back to verizon

I began having this problem with comcast and hotmail just today. I have been emailing fine for weeks...(3 weeks as a new comcast highspeed user) and today, I have had this '550 permit denied' message.

Has anyone figured out how to get around it????

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

The permit deny errors or occuring for MSN/Hotmail domains for severail major ISPS. This current batch can be blaimed on the sobar virus making the rounds and contributing to excess mail inbound traffic to MSN/Hotmail which the provider, frankly is not able to handle. Therefor they bounce all messages--legit, spam, or sobar spawned, back.

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. Partial headers of a recent email:
Return-path: <%User_ID%@comcast.invalid>
Received: from sccrmhc11.comcast.net (63.240.77.81) by aosake.net (Mercury/32 v4.01b) with ESMTP ID MG00000D;

X-BLTSYMAVREINSERT: 5Qo7tdSIR0PnmTMiGGPFPpzXY7gA
Received: from Office (c-24-6-41-96.hsd1.ca.comcast.net[24.6.41.96])

Message-ID: <013601c5f2bd$51e637f0$60290618@Office>
When the Comcast output server, sccrmhc11.comcast.net, connected to my "aosake.net" MTA, it issued "EHLO sccrmhc11.comcast.net" during the SMTP transaction. For my MTA, that is good enough. For an MTA doing DNS lookups, they will get the same result as Sam Spade gives me on a DNS lookup:
11/30/05 09:27:49 dns 63.240.77.81
nslookup 63.240.77.81
No reverse DNS (WSANO_DATA)
Some MTAs will reject that connection. You can't force the receiving mail administrator to accept connections he doesn't want to accept. If you can't convince Comcast to adjust their DNS record for that IP address, you are out of luck, as far as sending email is concerned. Which output server you get is not under your control. You can't even control which Comcast submission server you get. My correspondent got "sccrmhc12" on this draw; but, 43 minutes later he got another, "rwcrmhc14":
Return-path: <%User_ID%@comcast.net>
Received: from rwcrmhc12.comcast.net (216.148.227.89) by aosake.net (Mercury/32 v4.01b) with ESMTP ID MG00000F;
26 Nov 2005 11:54:29 -0800

Message-ID: <000701c5f2c3$51e93670$60290618@Office>
Sam Spade lookup on this Comcast output SMTP server:
11/30/05 09:27:20 dns 216.148.227.89
nslookup 216.148.227.89
Canonical name: rwcrmhc14.comcast.net
Addresses:
216.148.227.89
This time the DNS lookup matches the SMTP EHLO string; not like the first example.

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

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.

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.

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!

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!!!

Anyone relying on an AOL or Hotmail account for any sort of critical communication is asking for disappointment. I know you can't control all the choices your customers make, but you can help educate them.

I'm reading this thread because I just got an email from a client who can't send from her comcast address to hotmail addresses. I explained the situation and suggested that she would have fewer problems if she used her business email account rather than Comcast.

Yes, Hotmail and AOL addresses are free. If you drive a Yugo you can't expect Mercedes performance.

But Comcast is charging at least $42.95 a month for a badly configured SMTP server...
