Re: [E-mail] Microsoft Hotmail Blocks Comcast Traf
Norman
What I did was send my test message through one of my Comcast accounts. One was to a Yahoo address, one to my MRB addy and one to my bigfoot addy. My bigfoot account is set to forward to three accounts.(Yahoo, MRB, and a Comcast acct) I guess it looks like MRB rejected the bigfoot email, which in turn was returned back to me with the error message. |

| Actually, the Comcast notice tells you the reporting MTA, which is the one rejecting the email. If MRB was rejecting the message, the Bigfoot MTA should have sent the Delivery Failure Notice directly to whatever email account you gave them for notifications. Then you would have a DFN from Bigfoot, which identified the reporting MTA as a MRB server.
At least, I think that is what I am seeing. Or did the notice you cited not come from <MAILER-DAEMON@comcast.net>?

And while I'm at it how did you get your post to me to include the contents in between these symbols? Crap I can't get them to post. The greater than/less than symbols aboce the comma and period. When I copy and paste this mail stuff that info gets deleted from my post! lol |

Norman,
May I ask what your profession is? You have an awful lot of knowledge about the intricacies of email. If not already, you should put it to good use. I know I am at least in awe of all your knowledge. (I need to goto email/spam school)

Re: [E-mail] Microsoft Hotmail Blocks Comcast Traffic
** WORKAROUND **
Until they sort this out, you can use 216.148.227.125 in place of smtp.comcast.net for your outgoing mail. It isn't being blocked by Comcast -or- by Hotmail.
It identifies itself as rwcrmhc12 ... I think Comcast may have juggled their name and IP assignments and it has everything confused!
But if you don't trust me (and you shouldn't), you can verify that it's a legitimate Comcast server here:

There appear to be a pair of IP addresses associated with that server:
12/01/05 20:06:16 dns rwcrmhc12.comcast.net
Canonical name: rwcrmhc12.comcast.net
Addresses:
216.148.227.85

.85 is the one that worked in my test. 216.148.227.152 doesn't answer at all.
Hmmm.
.125 works
.152 doesn't
Might be a coincidence or might be a typo.

Little Rock, AR | A little earlier some of the posters on those Comcast Forum threads were reporting that mail is now going to Hotmail from Comcast. Maybe the blocking has finally stopped. |

Nope, still blocked. They must have hit the lucky #12 server in the rotation. I found it by repeatedly trying -- because I saw that once in a great while, the mail would actually go through.
Besides, don't you know that server misconfigurations take more than two full days for experienced, qualified engineers to fix?

| Jeesh then I wonder how many days it's really gonna take? lol
Luckily I use Yahoo for my smtp server. I don't see any of these Comcast issues. I also stopped using their DNS servers months ago. You know the old saying, fool me once, shame on you, fool me twice, shame on me. |

You know if Comcast allows use of any alternate ports besides 25? I wonder if using an alternate port will also do the trick? |

As I posted on 2005-11-30 19:14:22, on the third page of this thread. I used port 465 (with SSL) for sending a test email to an MSN Hotmail account. It depends upon which Comcast output SMTP server you draw in the lottery; my first attempt failed, as you can see in that post. See funchords posting about the one Comcast output server which appears not to be blocking email to the MSN MX servers. That server appears in the headers of my successful send.

2 edits | They are saying now on the Comcast Forums that the blocks are starting to be removed from the smtp servers. Letting the mail trickle out now. It seems instead of removing all at once they're doing em a little at a time.
Won't do any good to test anymore!
And just read this on the Comcast Forums:
"Since I've had Comcast, I setup my Comcast e-mail so all e-mail sent to my comcast.net address gets forwarded to my hotmail.com address.
For the past few days, if anyone with a comcast.net address tried to send me an e-mail directly to my hotmail.com address, they'd get the 550 error. But, if they sent it to my comcast.net address, it would successfully get forwarded to my hotmail.com address. Strange, I think."
For crying out loud, another workaround! |

Re: [E-mail] Microsoft Hotmail Blocks Comcast Traffic
As of noon on Friday, the email from Comcast to Hotmail/MSN seems to be working again. I've sent two emails to Hotmail accounts, and both got through okay. |

Re: [E-mail] Microsoft Hotmail Blocks Comcast Traf
I can confirm that an email that was stopped has now been sent as of 12/2 1:15PM EST.
I had asked for the issue to escalated to Comcast managers as I was not getting any useful status from Comcast. This was the reply:
Thank you for contacting Comcast. My name is Richard and I will be pleased to assist you today.
Re: What is the status with this issue? While the majority of issues can be addressed via email correspondence, we are unable to address this issue from within the email forum. Please contact our technical support group at 1-800-COMCAST for a more free flowing dialogue.
Translation - we have something to say to you that we are not comfortable putting in writing 
We can all read what we want into that - and no, I'll not waste any more of my time vainly pressing digits on my phone till the cows come home... |

I just tested using rwcrmhc11, a server that was previously rejecting the hotmail-bound traffic, and it is working fine now.
