I am not a mail server admin, however I've been given the task to migrate our company's current qmail server (running on Ubuntu 8.0) to a new Redhat Enterprise Linux server (RHEL 6.2).
After doing some research it seems that qmail is no longer being supported so I was thinking about installing Zimbra on the new server and then migrating the qmail users/mail boxes over to the zimbra server.
The current qmail server has 500 user accounts does not have any virtual domains nor aliases created.
We use courier-imap for user access with maildir as the mailbox format, and the mail accounts are created through an LDAP server.
My question is: What would be the best approach of getting all of the qmail server stuff over to the new zimbra server?.
Do I just need to copy everything and then change the MX record to point to the new server after everything has copied successfully?
