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.

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.

As 2025 comes to a close, we reflect on key events in the email and collaboration industry, and how they are shaping the future of email. We also discuss how our products have evolved, and what’s in the works for 2026.

Effective monitoring of MDaemon can save administrators time by alerting them to issues before they become outages. In particular, MDaemon provides a suite of built-in alerts, reports, and notifications covering everything from email authentication to system health. Enabling these tools helps catch problems early – for example, detecting spoofed mail attempts via DMARC reports, blocking brute-force attacks with Dynamic Screening alerts, and warning of low disk space or failed updates on the server. Below we explain each type of alert/report, what it means, and why it matters.

If you manage a mail server, having a functional postmaster alias isn't just a best practice—it's a requirement. According to RFC 2142, every email domain must have a working postmaster@yourdomain.com address. But beyond compliance, this simple alias plays a critical role in maintaining healthy email communication and managing server-related issues.

In an earlier post, we discussed six security benefits of choosing an on-premise email solution over cloud-hosted solutions such a Microsoft 365. Today we discuss the customization & integration benefits of choosing an on-premise email server over cloud hosted email.

Email is still the number one way attackers get into an organization. In 2025, the FBI’s Internet Crime Complaint Center (IC3) logged more than $20.8 billion in reported losses, a 26% jump over the prior year, and business email compromise (BEC) alone accounted for roughly $3 billion of that total. For managed service providers (MSPs), those figures are more than an industry headline. When a client gets hit, the MSP is the one who has to explain what happened, clean up the damage, and answer the hard question of why the defenses did not hold.

Now that the Covid crisis is behind us, remote and hybrid work is no longer an emergency arrangement, yet many people continue to work from home as it becomes a more widely-accepted practice. According to Gallup's latest workplace research, roughly 52% of remote-capable U.S. employees now work in a hybrid arrangement and another 27% are fully remote, leaving fewer than one in four back in the office full time. The U.S. Bureau of Labor Statistics reports that more than a fifth of all employees still telework at least part of the time. After years of return-to-office headlines, the data shows hybrid has settled in as the default for knowledge work rather than fading away.

 

A brief glance through my spam folder in MDaemon Webmail recently reminded me of the need for on-going education on the topic of phishing and Business Email Compromise (BEC) scams. I’d like to be able to tell you that the recent crush of cyberattacks on the healthcare sector, as exacerbated by the COVID-19 pandemic, has run its course – but then I’d be the one scamming. Looking through the latest Health IT Security monthly news archive turns up a long litany of phishing, ransomware, malware, spoofing, password theft and other data leaks, and server vulnerabilities that affect millions of patients and financial donors – and it’s not even the end of the month.
