Hi there,
I just completed a test run of the new version of iRedMail. The new script is able to correctly create all the objects in the postgresql DBs even with version 8.4.20.
To add a few finer points:
the stock rhel 6 (minimal install) is not enough on its own, you need at least the openssh-clients and wget packages, then you have to add the EPEL repository and at least the following packages from the "Optional" channel from RedHat:
libc-client-2007e-11.el6.x86_64.rpm
php-imap-5.3.3-40.el6_6.x86_64.rpm
php-intl-5.3.3-40.el6_6.x86_64.rpm
php-mbstring-5.3.3-40.el6_6.x86_64.rpm
After this, the main scripts can do its job. At the moment, however, I have RoundCubemail up and running, but not iRedAdmin (I still have to check the rest of the component services). I found the httpd DocumentRoot parameter set to /var/www/html, which is wrong, but fixing it is not enough; I'll have to do a little more checking to see what the problem is. I'll keep you posted.
Best Regards,
Alberto M.
