How would I go about removing all software/changes made from https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/
Restore the backup you took before installing ISPConfig. Or failing that, read the ISPConfig Perfect Server guide from the end to the beginning, and undo the installations and configurations you made. Start with running the uninstall-script that comes with ISPConfig installer package. Did you get ISPConfig working? If yes, then uninstalling ISPconfig probably makes all services fail, so you have to setup them yourself.
