I am giving up... and starting from scratch again. Any insight to offer? My plan is:
I have to leave the sendmail server as the primary mail gateway for the kccjs.org domain between the Internet and the network. Leaving the local DNS MX entry to point to the local internal address of the network ( mailgate.kccjs.org).
Reload Zimbra from scratch on the zimbramail.kccjs.org
Configure the zimbra load to be the kccjs.org domain.
Follow the Instrcutions of the Wiki for Split domain's, making sure to turn off DNS lookups.
Setup a local user on the zimbra mail server through the web interfaces.
Reboot, and try sending mail again. Hopefully it will not get bounced.
Cross my fingers.....
