Our server got corrupt. Long story short is none of the virtual hosts could send mail out. We ended up reloading a server with centos5 and vmin pro. Now I need to restore the users maildir from the old server to the new one.
I am unexperienced on is backup restores in virtualmin as a whole and have a fear bringing problems from my old server to the new one.
I have manually recreated all virtual hosts and websites.
