I've noticed that you have successfully helped others with this issue.

Emails sent from our domain is not delivered at Comcast.net

I can provide your further details.

I've already opened up two cases via https://postmaster.comcast.net/block-removal-request.html

Someone is suppose to call me back and no one has called back.

according to above link we're not on blacklist via IP however our domain is blocked!

Can you or someone help me resolve the issue please?

@BeGoodDoGood can you also provide the emails you are seeing the failed delivery to? im seeing a significant amount of successful deliveries to comcast.net addresses. Please PM me the emails you are seeing issues sending to.

@ComcastCSAEmail I am having this problem too. I don't see a way to PM anyone when I click on their name, so if you need me to PM you you'll have to tell me how.

I am trying to send emails from chris@customdeckworks.com to my comcast.net account and they aren't showing up. They are not in spam or junk. I have Outlook set to send my delivery receipts and I don't even get those after sending. I have a feeling all the emails I sent will show up all at once, like they are bottle-necking somewhere and just haven't made it through yet. 
If I can't get these emails, then that means my customers that also use comcast.net can't get them either. And that's a problem!

In the last 2 days, one subject from chris@customdeckworks.com to my comcast.net account was "Rally Stripes", one was "Car Stripe", one was "Edit & post this", and one was "Doggy".
I'm not sure of the last time I could actually send to comast.net. But on Jan 23, 2020 I sent a Block Removal Request to postmaster.comcast.net. I never heard back and now I can't remember if it got fixed and so it's messed up again, or if this is still not working from then.

Can you help with this?

@deckster the Comcast.net server has not seen communications from your domain in the last 30 days. The issue is not on the Comcast side since we never got a notice of delivery from your server. Its possible depending on the service you are using that they are being blocked before even leaving the server.
