Hello

how can I set the email system correct to redirect the incoming mails to the specific partner. The mail should be automatically create a new record in the message box under the partner. 

So if a mail is coming in the mailbox with partnerA@A-domain.com. The mail should also appear in the partner A message box. If partnerB@B-domain.com is coming in the inbox, the mail should appear only in partners B message box.

Please help me.
