Often mail clients delete the mail from the server *after* retrieval. This is to reduce you mailbox size at the remote server. You often have a quota, if you go over that quota then mail bounces. Spammers get wind of this and use the desired recipient as the 'mail from' and send mail to your over flowing account. The mail can't get delivered due to quota, and the innocent person in the 'mail from' gets the spam content. This is called back scatter spam. The Apple client is probably removing mail when it is downloaded to reduce mailbox size. Ed
