MDaemon includes a built-in Web Conferencing Server (added in version 25.5.0), allowing users to start audio, video, screen sharing, and chat sessions directly from MDaemon Webmail. Because the entire system runs on your own server, no conference data passes through a third-party cloud service unless you specifically choose to add one.
Email is still the backbone of business communication, which means an email outage is rarely a minor inconvenience. When your mail server goes offline, orders stall, customers wait, and internal work grinds to a halt. That’s why failover and high availability (HA) should be considered with any MDaemon deployment plan.
The good news: achieving high availability with MDaemon is far simpler today than it used to be. This guide walks through your options, explains how to choose the right one, and covers the planning and testing that separates a resilient setup from one that only looks redundant.
Email is the backbone of how your organization communicates, but the server behind it shouldn't be complicated, expensive, or something you have to think about every day. That's the idea at the heart of MDaemon.
When an MDaemon service stops unexpectedly - SMTP, Webmail, ActiveSync, or any of the others, every minute of silence is a minute your users aren’t sending or receiving mail. The good news is that you don’t need a third-party monitoring tool to catch these events. Windows ships with a built-in feature,
Performance Monitor, that can watch for a stopped service and send an email alert the moment it detects one.

This guide walks through the full setup end-to-end: creating the performance counter alert, adding it to a PowerShell script that sends you a notification email, and testing the whole chain so you can be confident it will work when you actually need it.
Many of our customers are using both MDaemon and SecurityGateway™ together for their email security and messaging needs. Both products are loaded with anti-spam, anti-spoofing, encryption & other security features, and while some features are unique to MDaemon or SecurityGateway, many are found in both products, and therefore can be disabled in MDaemon as long as they are enabled in SecurityGateway.

While it may be more common to move to MDaemon from Microsoft Exchange or to move MDaemon from one server to another, it's also possible to move a single domain from one MDaemon server to another - without migrating the entire server.
