Depending on your MX settings, I am guessing they are still pointing to the Qmail server, you need to have Qmail relay the accounts on Zimbra to your Zimbra server. There are many articles on this. For example when I migrated from hosted Exchange I had my Exchange provider relay any address that didn't exists to our Zimbra server. I then moved my MX to our Zimbra server and any account that didn't exist on Zimbra relayed to my hosted Exchange. If you setup split DNS locally, that will not change anything on public DNS records you have setup. |
