How can i retrieve my old email as my former wife deleted my mail box in early june 2007?

There are a few places you can look, if it's still there, to try and get it back, but if she deleted your account all together, the only thing you can do is open a new account with a new ID and password, then build your address book. When you do, don't forget to sign out each time you leave the computer. Check the "Bulk" folder in case she just spammed them. Check the "Trash" folder. If she didn't delete it after deleting the email, it might still be there, but yahoo has a policy of deleting the "Trash" folder automatically after a length of time. If you can still get into your account, click on the "Options" link in the upper right of your yahoo mail page. Then click on "Block Addresses." Highlight the addresses you want back and click on "Remove Block.
