Greetings,
I am reading documents on installing iredmail, then upgrading to iredmail pro.  Do you need iredmail to install iredmail pro on a clean system? or does iredmail pro have all the features on installation.  The reason why I ask, is there is no bash file iredmail.sh in the root folder of the tarball I downloaded?  Thanks
