URGENT: Still having email issues? Post your email status here! Refer Cox Support to this thread.

Since the 4/24/19 email security rollout, users have been experiencing various kinds of email issues. This is now day 13. I can receive email, but when I send email, it shows in my sent box, but is not received by the intended recipient. It is stuck on the Cox email server. My IP address is not blocked, I verified that. This is happening on my new iPad iOS 12.2 and on Cox’s WebMail page, no matter what browser I try. To date: nothing has been resolved. Every fix, workaround, password change, delete and re-entering email address, blah-blah-blah, etc. has failed. Been working on this for 12 days straight.

Please, I would like to hear from all of you what your current status is concerning your email and, if any, what fixes have worked for you.

Please keep the responses coming, we’re really starting to get some strong answers to the email issues supplied by us, not Cox. Awesome!!!

You can also see it in a tracert. Notice at hop 6 it leaves Cox and is on a provider called RackSpace. Don't know if they are the email provider or network provider for the email provider, but the thread you quoted shows it's now a partnership.

FYI that was a tracert from my computer to imap.cox.net. The confusing part is because of the "partnership" they made changes in DNS too.

C:\Users\>nslookup imap.cox.net
Server: router.asus.com

Non-authoritative answer:
Name: imap.east.rs.oxcs.net <==
Aliases: imap.cox.net

Notice how imap.cox.net automatically redirects to the new domains on oxcs.net, which is not a Cox server.


Thank you all in advance.

  • Given the length of this discussion - I'm not certain where best to post my on-going email issues - but would welcome any feedback which might help me address the unresolved concerns I originally posted a month ago:  https://forums.cox.com/forum_home/internet_forum/f/internet-forum/22880/trouble-getting-emails-sent-via-apple-mail-and-via-my-email-cox-net  which relate directly to this discussion.

    After changing the port from 465 to 587 (with TLS enabled) - and only accessing my email account via myemail.cox.net, I thought my email troubles were resolved as I would no longer get the pop-up message:  

    ! An error occurred inside the server which prevented it from fulfilling the request.

    But I’ve since learned that a large majority of my emails (not all) do not reach their destination.  They show up in my “sent” folder - but the intended recipients have repeatedly confirmed they are not received.   Since my troubles began, I’ve made it a practice to bcc my husband’s work and Earthlink.net email accounts - as a check to see if my emails are getting out.  He receives the blind copies of my outgoing emails just fine - but the intended recipient doesn’t receive my email.  What makes this so hard to trouble-shoot is the fact that other emails to other parties go through without issue.  The only standout detail that I’ve been able to identify with two of the recipients who are not getting my emails is that both have Comcast accounts (one is in TX - one in PA).  Don’t know why this should be a factor - but throwing this detail out there just in case anyone can shed some light on how I can fix this.   Thanks in advance for any guidance that can be provided.
