SENT Emails Successfully Reaching bcc parties but NOT the intended "TO" recipient

Hi MissyKay, I believe I have replicated the issue where an email sent from an @cox.net address via Webmail to an @comcast.net address does not arrive at its destination. I was able to test this yesterday by sending test emails from my @cox.net email account to two different @comcast.net email addresses. The friend/owner of the 2 @comcast.net addresses reported that neither of my emails arrived in her Inbox, trash, or spam folders. I'm going to submit an escalation ticket to our email administrators for further investigation. So that I can include your information in the ticket, please follow the steps below to gather and email me (Cox.Help@cox.com) the details listed below.

Log into your Cox Webmail Inbox and click on the Sent folder (sometimes called Sent Objects).
Click on the most recent email sent to an @comcast.net email address (that you know did not arrive at its destination). The email will open.
On the right-hand side of the email, click on the More Actions icon (three horizontally stacked lines), and then select View Source. A pop-up window will open.
Click once in the gray-shaded section of the pop-up window.
On your keyboard, press CTRL and the letter A at the same time. Everything in the gray-shaded section will turn blue.
On your keyboard, press CTRL and the letter C at the same time. This copies the text.
Click the Close button to close the pop-up window.
Underneath the top blue bar of your Webmail window, click on the word COMPOSE.
Click once in the body of the email, and then press CTRL and the letter V at the same time. This will paste the text into the body of your email.

Do this for each of the @comcast.net email addresses have not received your sent mail. This will provide me with a large amount of data for our email administrators to review, and will hopefully expedite a resolution. It may take 4 or 5 days, but as soon as I have further information, I’ll let you know. -Becky, Cox Support Forums Moderator
