To protect myself from ATT's Yahoo Mail problems I have had to periodically throughout the day use my web browser to view what emails were on the server verses what was on my email client.
Today I noticed an important email in the Trash folder of their server. Dang! So I told the server to move the email to the Inbox of my server, which it did. Then I looked my email client and there was nothing so I went back to my web browser to check the Inbox and the email was gone.
In the past month I have had nothing but problems of disappearing email and email incorrectly identified as Spam.
My only recourse is to post this. Of course I could use the Chat but I do not have the time or patience to deal with someone who only asks the obligatory, standard 25 questions that have nothing to do with my issue.
