Email from a custom domain suddenly not received

I have a custom domain I use for email. Email to this domain is forwarded to my comcast.net email address by my domain host, godaddy. Recently (last week or two), email I send from my domain to someone on my domain is lost with no error returned. When I send to any other email address, even my comcast.net address directly, the email is received. I use smtp.comcast.net to send the mail. My domain DNS Sender Policy Framework (SPF) record is set to match the comcast.net. I receive all other email via my forwarding service, including plenty of spam, but for some reason my legitimate emails are be trashed.

Thanks for providing those details. I can see why this would be frustrating when email from your custom domain is reaching other recipients but messages sent between addresses on the same domain are not being delivered.

Based on the information provided, this does not appear to be a general Comcast email issue, as email sent directly to your Comcast address is being received. Since the issue involves a custom domain and third party email forwarding, we recommend contacting your domain host or email provider to investigate the delivery failure and review their mail logs. They will be in the best position to determine what is happening to those messages during delivery.
