I want to Zimbra to only receive and send email using our existing domain POP and SMTP servers (eg: mail.domain.com for both servers). This is my 3rd install of Zimbra just trying all of it out. *LOL uninstalled it but postfix was giving me issues so i started fresh*. I have successfully setup SMTP authentication and my setup of fetchmail has been hit or miss. I have since change my domain MX records back to the way they were originally. Is there a way to have Zimbra receive and send without making changes to our MX and A records. All i want is to send and receive email at this time. I will be using getmail this time because of recommendations in the forums. We change the MX and A records back because the changes killed some of our sub-domains we had setup.
