title: Transfer ownership of hosting keeping emails and delete them on server
body: <p>A client of mine is selling his business and he will transfer he's hosting with website and email adresses to the new owner.</p>
  
  <p>My client wants to keep his emails on his computer and delete them on the server before the new owner takes over. </p>
  
  <p>However I'm not sure what is the best approach because there will be backups. My client doesn't want the new owner to have any possibility to read my clients old emails from backups.</p>
  
  <p>What is the best approach, is there any differences if the emails are setup for POP3 or IMAP ?</p>
