I have just 1 yahoo account but somehow i get 2 notifications for every e-mail.
1 is grey and the other is purple if that helps.
They both look different when you open them.
Really annoying.
Hum one is grey an one is purple did you by chance get the Yahoo app from the Market maybe ? i will have to think on this one a bit as i don't remember mine ever showing this..b33
Did you install a 3rd party email client like K9.. if so then you will have notification from it and stock app.
To fix you can open stock email app and select Menu/ Settings / Notification and unchecked option.
