Webmail showing "500 internal server error".
In Apache logs, I can see:
tail -f /var/log/httpd/error_log
[Thu Dec 05 17:21:00 2013] [warn] [client 18.104.22.168] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server [Thu Dec 05 17:21:00 2013] [error] [client 22.214.171.124] Premature end of script headers: index.php

You need to remove the symlink and change the vhosts location by using the
