Emails sent to any comcast.net email is being rejected

Today I was informed that someone tried sending me an email to my comcast.net and they got a rejected email message. I then tried sending emails to multiple comcast.net emails right now from various domain emails and gmail, outlook etc and they all get rejected back immediately to the sending email address. 

Your message was rejected by the recipient email server. Please check the recipient's email address and try resending your message, or contact the recipient directly. For more tips to help resolve this issue, see DSN code 5.1.0 in Exchange Online - Office 365. If the problem continues, contact your email admin.

resimta-h1p-037584.sys.comcast.net gave this error:

<email removed>  sender rejected

Is there a Comcast outage?

Hello @kilthro thank you for taking the time to make this post to share your experience to bring this to our attention! We want to ensure this is working as you need! I checked our current known issues and I am not seeing anything posted for email issues. I did see you mentioned below that you got an email to go through. Is everything working as it should for you now, or are there still some emails that are not going through successfully?

Hi there, things have appeared to be working just fine since 9:30 pm on January 30th. It was down for at least 30 minutes that day. Thanks for circling back.

I just got an email to go through. Maybe now its resolved or being corrected.. It's definitely a Comcast server-side issue.

@kilthro​ I just got the email notifying me of the reply!  A couple emails also went through.    But before that, mails were getting rejected for at least 20-30 minutes.

I am having the same problem.  Some emails that are being sent to me are being rejected by Comcast with the 5.1.0 error message (server rejected).  Not every email, just a few with attachments or links.  This has happened twice in the past days, not both at the same time.  I read that there should be a link in the rejected email that the sender can click to resolve. But there is no link.  t appears this is a Comcast issue where they have decided some emails could be spam.  Comcast, how do I resolve?

@user_illeuq​ That (specifically "server rejected") is not a message that our systems generate.  Is there a prior deferral message?  Can you tell me who the sending domain is for the message?

This is the message I have been getting for days. Any help would be appreciated

Your message wasn't delivered because the recipient's email provider rejected it.

Same issue. Some email sent to my @comcast.net address is rejected. I get letters from businesses (e.g., my bank) saying things like "We tried to email you, but it didn't go through."

I send email blasts through email software Iterable. For the past several weeks, comcast.net emails have been bouncing. Just since yesterday, I can track 1500 bounces. @XfinityAlex can you help me get my domain un-blocked? Our comcast clients are emailing us, upset that they aren't getting our emails.

Legit emails are being rejected but yet SPAM is getting through. How can I check what is being rejected? It is various people/businesses.

Your message to <xxx> was automatically rejected:

unwanted

Can't do a live aent chat, the IT Assistant won't pass it through.

All our sent emails to the users under "comcast.net" get bounced back! 

I have an identical issue. Whenever I try to send any emails to the comcast.net email address! I got the "resimta-h2p-561953.sys.comcast.net rejected your message to the following email addresses"

You need to send that information to @XfinityAlex in a direct message.

To send a direct message:
 
Click "Sign In" if necessary
 
• Click the "Direct Message" icon in the upper right
• Click the "New message" (pencil and paper) icon just to the right of Conversations
• Type "Xfinity Support" in the "To:" line not the Employee's name
• Type your message in the text area near the bottom of the window
• Press Enter to send it

Happening again. My gmail address is being rejected by my wife's comcast account (several attempts). It also happens when I try to send messages to my own comcast account from gmail. Something appears broken with Comcast email servers again.

I am also hearing from friends that emails sent to my comcast.net account are "message blocked" with technical information that "the response form the remote service was: 530 5.1.0 sender rejected" any ideas what to do?

I am getting messages blocked if I send them from my gmail accounts to my comcast.net addresses. 

Your message to ........................has been blocked. See technical details below for more information.

The response from the remote server was:

Same happening here now.  Email sent from any of my Gmail.com accounts to any of my Comcast.net accounts are being rejected by Comcast's servers and bouncing back to Gmail.  Error is:

The response from the remote server was:

530 5.1.0 <@gmail.com>sender rejected

Mail sent from my Yahoo email to Comcast is going through normally.

This is a problem that needs to be addressed with priority.  In fact, I have long had one of my Gmail accounts set to forward a copy of *every* email to one of my Comcast accounts.  That normally works fine, but right now all of the forwarded emails are being rejected by Comcast Mail.

Thanks.

@Rick441​ It's about 5 hours later and the issue seems to have resolved for me.  A test email from one of my Gmail accounts to one of my Comcast accounts went through OK instead of being rejected by Comcast's servers.
