I have installed and configured Zimbra for the first time.

I can send emails fine but can't receive any emails from any host.

My server is mail2.vpoffices.com.br. I also have another server running cpanel with emails for this domain. I am trying to create accounts in zimbra that differ from the names on the cpanel server and whenever I send an email to my domain whichever server has the account will receive the message.

My zimbra server passes mx test on the domain configuration page.

Can someon help me diagnose this problem?
