pop accounts fetching all in one inbox not different inboxes

Hello!

I try to configure my zoho-account.Sorry for my english, I'm from Germany and maybe I use the wrong words or terms.

I have a mail-adress at Zoho.com and two old mail-adresses, which i want to fetch via pop3 into my zoho-mail. It works to fetch the mails from the other adresses, but I have them in a different Icon on the left pane on my Computer and in a different account on my zoho-mail-app on my iPhone. I can't see them in my Outlook 2007 (i use Imap to sync with zoho).

What do I have to do to get all pop3-collected mails in my main-inbox in zoho, my iPhone and Outlook?

Thank You!

Moritz
