create a new account with exactly the same settings as the one you deleted.
username, password, server names, etc.
I still have Tiger on this computer. In Mail preferences and accounts I deleted my POP Verizon account since I changed providers. Instantly, every e-mail in my in-box and sent box dissappeared without any warning message. I have not backed up the computer for several months (I know - huge mistake), so I do not want to restore this way. The e-mails are no longer on the Verizon server. Is there any fix to retrieve my lost e-mails? I didn't empty any trash; it seems like the e-mails must be somewhere on the hard drive. Thank you so much for any suggestions!
