'''bold text''' All of a sudden today Saturday the 11th Thunderbird stopped sending email on COX but it can receive them. It was working fine then all of a sudden the sending of email stopped. At first I thought that is was Cox being down again, (I've had connection problems this week). But while I was trying to figure it out I received a number of emails. I tried sending a test email to myself usually they go right away but it did not go. I called Cox. They tech connected to my computer, made some checks, (updated Thunderbird) and after about 20 minutes it started to send messages. 10 minutes later it stopped working AGAIN. This started a four hour telephone marathon with just about every level of service that Cox has. I ended up with Complete Care and while I was on the phone with him and he was connected to my computer the service tech from Cox who was here to check my signal and modem showed up. He tried to look at the problem and could not figure it out. Note I can send and receive mail from the COX email website but and only receive email in Thunderbird. Cox tells me it is a Mozilla or Thunderbird problem I'm telling them it is not that it is a Cox problem because the server is SENDING me email to Thunderbird but the Cox INCOMING mail server it not connecting to Thunderbird to receive emails. They claim that because I can send and receive on the web page but can not send with Thunderbird. I'm telling them it is a Cox problem. Anyone else have this issue? Anyone have a solution? I'm shutdown here with over a 25 year history of emails sitting in Thunderbird. Al
