IP Shield is a security feature in MDaemon that protects local accounts by preventing malicious users from spoofing, or pretending to be a local user on your MDaemon server. With v12.5 MDaemon has improved this feature. This document shows you how.
We recommend to always use encrypted connections whenever possible. Setting up MDaemon's WorldClient (web mail) server to accept HTTPS connections costs nothing but the admin's time using a self signed certificate created within MDaemon.
