Recently all cox.net emails transferred to yahoo mail but kept the cox.net address. I prefer the Thunderbird format for emails, more options. How can I add them to Thunderbird? I already have them in Thunderbird with the cox.net address but no new emails are coming in on the ones that have already transferred to yahoo mail. (They didn't all go at the same time so I am still getting emails on the ones that didn't transfer yet.) Thanks.
