Undeliverable email messages

Question

There is a problem with my email account. When anyone sends an email to my primary address they receive an "Undeliverable" email back to them . In fact, I am receiving their email just fine. The Undeliverable message is being generated because Cox (for some reason) appears to be trying to send a copy of the original email to an old email address that is no longer valid. At the bottom of the Undeliverable message that's what's indicated. I've been on the telephone with Cox support on 4 separate occasions. Last time the call lasted over 3 hours (lots of hold time + talked with 4 different representatives). At the end of that marathon I was assured that the problem was fixed. But it wasn't. Any suggestions? Spending hours on the phone isn't solving the problem. Thanks for any help.

If the email is sending a copy to that email address, that would usually be a setting that is causing that. Make sure you do not have autoforward setup for this email address under webmail. Once signed in click the settings button at the top right (looks like a gear) and then settings. From there click Inbox on the left-hand side and then the sub menu 'Autoforward'. You may also want to make sure there are no other type of rules setup that could be forwarding the emails. This can be found in the same area, but under 'Filter Rules'

Thanks for your suggestion, Brain. When I look at My Profile I see that I have ONLY one email address. That's the one I use and that's the one my senders are using. I don't even see an auto-forward choice (maybe because there's no where to auto-forward to?).
I would love to simply send an email to some Cox support person describing the problem, along with a copy of the error message that my senders are receiving. I suspect this would be an easy problem for that person to solve. But I see no where that allows me to send an email to Cox support. It's either a text chat or a phone call.&nbsp;&nbsp;

Description of my on-going Cox email problem. This has been occurring for at least 3 weeks:
&nbsp;- My primary email address with cox.net is k0tw@cox.net. This is my ONLY active email with Cox.&nbsp;
- The problem surfaces when someone sends an email TO me. This has happened with emails sent from a number of people with widely different email addresses using different ISPs:&nbsp;
For example: If… let’s say… Jim@aol.com sends an email to me at k0tw@cox.net.
1) I receive Jim’s email just fine.&nbsp;
2) But within a time-frame between 5 minutes and several hours Jim receives the following message back in response to the email he sent to me:&nbsp;

This is the mail system at host mx-out.cox.rs.oxcs.net.I'm sorry to have to inform you that your message could notbe delivered to one or more recipients. It's attached below.For further assistance, please send mail to postmaster.If you do so, please include this problem report. You candelete your own text from the attached returned message.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;The mail system&lt;k0tw_macbook@cox.net&gt;: host 68.1.17.4[68.1.17.4] said: 550&nbsp; &nbsp; &lt;k0tw_macbook@cox.net&gt; recipient rejected (in reply to RCPT TO command)

------------------------------------------------------------------------
Notice that the error is associated with an email of k0tw_macbook@ cox.net which is an old email address that I had Cox delete a few weeks ago. Why is Cox (apparently) trying to send a copy of the sender’s email to this non-existent email address??
Thanks again for any help.

Hi Radiok0tw. You may want to check the forwarding option in settings to make sure that this isn't set up. - Lisa, Cox Support Forums Moderator
