I use Zimbra open source server and Zimbra desktop, i configured zimbra desktop with 2 account 1- zimbra email account , 2- pop3 email server with other email domain.

I need to configure Zimbra desktop to make the second pop3 mail account to save the incomming mails to Zimbra server account.

Note: i migrate my account from Microsoft Exchange server also i use Micrsost exchange account as backup server only and the host of mail server is hosted at outside hosting company.

how to make it ?
