Does anyone know how to change the primary domain? The install was done with Domain.local which has caused a couple problems.
1. the HELO is wrong (fixed by editing the /var/service/qpsmtpd/config/smtpgreeting) - but I have to do it again after updates
2. Horde uses domain.local as their default "from:"
Log in as admin and reconfigure your server, where you once entered Domain.local you will have to enter your real domain name and the configuration should be updated.
Next time you change the configuration files, make your configurations in the template system, this will save changes over reboots, upgrades and so on. For more details about the template system see the development section on the left.
