But the easiest way would be to create a own folder for each mail account and to install an individual incoming filter for each of it (of the type: "send mails with TO-address [EMAIL PROTECTED] to the folder XYZ"). The additional benefit of this is that you will named automatically as sender with your mail address of that specific account whenever you reply to a mail which went-in into the concerned account-folder.
