I used windows word, my Isp used pop 3
If you installed XP and reinstalled all your programs, then unless you exported and backed up all your e-mails beforehand, then they are gone, and I doubt your server would keep them that long.
You say you upgraded your computer, but no mention of any backups, whether the hard drives were replaced, formatted or kept as a backup.
Not enough information to make a guess if there is any chance of recovery.
