Email messages not being received by comcast customers

I have exactly the same problem.  The Comcast contacts I have do not receive emails from me.......I am NOT a Comcast customer and my email provider says Comcast has accepted them but did not forward to the addressee.....any suggestions?

i have resorted to using a secondary email sending address when sending to a Comcast contact but this is unacceptable in the long run!

Hi you guys! Thank you both for posting and welcome to the community. I was able to get @CCAntiSpam involved and they might be able to help you out. If you can supply them with the info they requested (when you get a chance) that would be awesome. Thanks!

In both cases, I'll need the domain for the sent messages.  I can take a look.

I have sent a DM to the @CCAntiSpam account as I didn't want to post my domain here.

Either put it in this thread, or send me a PM (Click on my name, and upper right should be a link for a Private Message)

Hi @CCAntiSpam ,

We started having this same issue within the past week. Emails are being accepted by the comcast mail servers, but are not showing up in spam folders and do not bounce. How can I send you the domain/ip information so you can look into this?

Thanks,

Michael

So what is the fix? 

I can get emails, but when I reply or send new ones nobody is getting them.   My outbox says they are sent.

@DavidinHartford Give it a try now.  I believe we've sorted out the issue.

@CCAntiSpam 

I am having the same problem...whereby emails sent to comcast.net email addresses are not being delivered.  I worked on this with Google, and they were not able to resolve the problem because everything on their end is configured properly.  I found a forum entry (https://forums.xfinity.com/t5/Email-Web-Browsing/Gsuite-Messages-not-getting-through-to-Comcast-net/...) from another user who had the same issue, and their domain had been flagged as problematic by Comcast.  Can you please take a look at my domain to see if we've been similarly flagged?

I am also a comcast customer although the domain we are trying to send from  is arae.com

Please help!

@CCAntiSpam  I am having the same issue.  I have already called the regular Comcast Business 800 # and they told me there was nothing they could do.  Other than they are aware and working on it.  For some reason I cannot see how to PM you.  Can you help me?

I responded to the PM that @EppingSeptic sent me.

Our email is getting to customers again.  I am not sure if @CCAntiSpam solved our issue since I didn't hear back after the mail started flowing.  I also had several other people looking at it as well.  Either way, I thank whoever helped us out.

Sorry, I thought I'd replied.  Yes, we esclated the issue and it should be resolved going forward.
