Why all my yahoo sent folder is deleted?

Yahoo mail: I accidentally sent all E-mail addresses to spam folder and deleted them. How to "recover" them?

• This morning, when I used Yahoo Mail, I intended to send one spam to the Spam Folder. Unfortunately, I accidentally checked the "select all" check box. Thus ALL my E-mail in my Inbox were sent to the Spam Folder and were deleted in the Spam Folder at once ! I immediately change the setting of my Spam Folder from "delete at once" to "store for 1 week before delete". Thereafter, some E-mail sent from my friends to me were sent to my SPAM Folder directly (instead of Inbox) I cannot find the E-mail address of my friends from the BLOCKING list in Yahoo mail. Can I "recover" these E-mail addresses from the Spam Folder? I don't want all the E-mail from my friends to be sent to my Spam Folder in future ! SOS ! Please HELP !!

• Answer:

  Your out of luck in so far as recovering those addresses. Do you have at least some of them in your address book. If so you need to let the spam filter know those addresses are not spam and to send them to your inbox. You could enlist the help of your friends to share their address books and rebuild your own. This is the only way I know of to restore what you deleted.
