I set up a new server from scratch with CentOS 5.4.
I then installed virtualmin as directed via the command line.
I then performed needed updates, which all completed.
upon creating new virtual servers, none of the email associated with those domains would work - neither in email clients, or even usermin.
Some Googling showed that a change in DoveCot needed to be done, manually adjusting it to just go to ~/Maildir
Why is this needed on a virgin, out of the box, new installation, on the approved and suggested operating system?
