Cannot receive email sent from charter.net email addresses

@bwhiten​ any suggestions on how we determine the fix?

I am having this Charter person send me emails to see if it ever works but I have no idea how to press the issue with either Charter or Comcast.

@bwhiten Thank you for reaching out to us here so we can figure out what's going on with your Emails sent from Charter. Are you able to send Emails to Charter customers? Is this isolated to your Comcast Email?

I have been chatting (Direct Message) with Xfinity Support. They assure me that CSA will call me by Monday tomorrow (1/8). That is OK with me, but I do not see what value a call has. I have already posted all relevant info and there is nothing more I can tell them. The problem is obviously not on my end. I see the problem with webmail as well as with an email client, but focus on webmail so that we can remove the client from the discussion ... so that I do not get advice from them to check my incoming and outgoing server and port numbers, which have no meaning for webmail. I have talked with CSA twice before about this very same issue with no resolution. Their conversation with me seems to focus on verifying my account.

The undelivered mail does not reside in any SPAM or JUNK folder. It is not filtered.

One very interesting observation ... I have sent (by hand, not a script, but one after another) mails from charter to comcast. I do this in blocks of 10, 20, or 30 emails. If I just send one email it never arrives, But if I send several one after the other, I noticed that about 10% get thru. Does anyone have an explanation of why this might be true? I have consulted with some colleagues and former co-workers (especially the ones smarter than me) and they tell me it could have to do with the unique properties of a firewall sent up by Comcast but that without knowing the details of that firewall, there is no more they can say.

This is excellent information, tkubaska. I have had a similar experience but you have gone further by sending copious emails to Comcast to gather more information.  I believe it is a firewall issue as well, but the Comcast folks shouldn't need us telling them what's wrong.  I feel we've all done a significant amount of troubleshooting to help them identify and correct the problem.  This issue is not getting the attention it deserves. 

As much as the two companies dislike each other, you would think they would scramble to at least PROVE the other is at fault.

But instead they just blame with the hopes its never solved and found to be their problem.

I have the same issue - don't receive email sent to my comcast.net email address from a charter.net email address.  Issue began in the same time frame (last success receipt was 11/21/23).  

@user_k99zqy Hello, I am happy to be of assistance. Can you please send us a DM. You can start by clicking the chat icon located in the top right corner of your forums' page when signed in. Once there, you can direct your messages to "Xfinity Support." Please add your full name and service address to help us locate your account. Let me know if you have any questions. 

I hesitate to mention this; but miraculously it started working for me this morning.   fingers crossed that problem has been fixed.

@user_mf15sg That is definitely great news! It could have been a combination of mail servers being updated in the backend so if that has been completed, it certainly makes sense that email would start functioning normally. If you experience any other issues, please let us know. Have a great weekend! 

@user_cfb1c5 Hello! Thank you for reaching out to us here on our Community Forum. We are aware this has been happening, and we are hearing that the issue has been resolving on its own. It may take a few days to resolve but this does not appear to be a long-term problem, and we are sorry for the inconvenience.

@user_cfb1c5 Excellent! Thank you for letting us know, and we appreciate your patience while that was worked on. Have a great rest of your week!

Nope, still doesn't work.  My Charter.net contact just sent me an email. I logged out of my account, closed my browser, restarted my PC and brought everything back up to find no mail was received.

For some reason Comcast's servers are blocking packets from Charter.  Correcting this issue shouldn't be a problem.   

I apologize that you are still experiencing issues with your email. I would like to take a deeper dive into this for you.

@XfinityMarcus​ 

I tried the link and it took me to a 404 Error page…

@user_ht2h51, my apologies the link must have broken after sending. Can you try this one instead? 

@Again​ Thank you!  I will DM @XfinityAlex

Thank you very much for taking care of this.  I appreciate all your help and responses.  I'm glad to know there is a place to go where these sorts of problems can be solved.  Thank you again and Happy New Year!
