When I first installed Zimbra I accidentally set the domain incorrectly:
mail accounts should be email@example.com, but I screwed up and it was
I fixed it at the time (thank you forums) by creating domain.com, and moving all the users to the domain.com domain using CLI.
Problem when upgrading is it is trying to do things like create admin, spam, and ham accounts with firstname.lastname@example.org, email@example.com, and firstname.lastname@example.org.
What / How do I fix the config files to this (they are used by the installer for upgrading).
