Not receiving emails on my comcast.net account

I am using Thunderbird app on Windows 10. I checked my spam folder on comcast.net in the browser and there were only emails from those that I have marked spam. The emails I sent from my gmail account are not showing up in either place.

@Garydj1950  Can you do me a favor and make sure that email forwarding has been turned on. To do this, you'll want to access your comcast.net email through the browser and click on the "settings" gear icon" and click on "Email Settings", then "Auto Forward". Remove anything that may be input there. There's also instructions on doing this by going to this link https://www.xfinity.com/support/articles/xconn-auto-forward. Another thing you may want to check is to make sure there are no email or spam filters setup that may be inadvertently sending your emails to the trash folder for example. There's some instructions on those settings at this link https://www.xfinity.com/support/articles/spam-filters-and-email-blocking-new-experience. Let me know if you're noticing any setting that may have been conflicting with your emails. 

Auto forwarding is not set and only one filter. It's for a specific address that I can't stop them from spamming me.

Also, I get no error codes back from my gmail that I send to my comcast.net address.

@Garydj1950  I appreciate you checking those things and confirming for me. At this point, I'd like to take a closer look into this with you. Please send us a Live Chat with your first and last name as well as your service address so we can assist.
