Can't send email

About a week ago (probably coincident with the April 24 Cox email security change), I have been unable to send emails from my Cox account using Outlook.  I created a new email account on Outlook, and have set it up per Cox instructions (POP, pop.cox.net, port 995 - smtp.cox.net, TLS, port 587).  The receive email function works, but it fails every time it tries to send an email.

  • You are not alone. It works on wifi, but not on phone data connection. Authentication error when trying to adjust server settings, or I'll send that message when you have a network connection again.... and I already have data connection. After re-setting multiple email accounts on android devices and even reinstalling t-mobile email app it becomes apparent this issue is limited to cox.net outgoing email. Gmail works. Cox.net only works on wifi.

      I am also having this issue.   I also have an open ticket since 4/25 and no reply yet.  Using Thunderbird 60.6.1, also failing on my iPhone running basic Mail.

  • Same here with MacMail. Blocked IP is the error I see in my Mail Log?  I can't get anyone at COX to give me an answer...Hell, I can't even get anyone at COX to respond.

    I can send and receive from home using the same version of Mac Mail with all the same settings. At work, I can't connect to SMTP.

      I also have the same problem.   I can’t send email from the mail app on my iPhone when I’m on my work Wi-Fi.     If I turn off Wi-Fi it works ok.   When I’m home on my cox network Wi-Fi it works ok.     

      This was all working ok last week?    Why can’t I send email only when on my corporate work Wi-Fi?
