I am a newbie to Zimbra using Zimbra 6.0. In my company I use qmail up til now and through pop3 I download emails for all our accounts from the email server of our provider (lies on the Internet on the address

Please can you help me how to configure zimbra to download emails from our provider?

We also sent all emails through smtp server of our provider that is authenticated. Can you help me please where to set up smtp server so that all emails are sent to and authenticated with login and password different from the one for the local email account

Thanks a lot
