In an age where cyber threats are growing in both sophistication and frequency, securing your email infrastructure is more important than ever. MDaemon includes a variety of tools and settings that can help administrators protect their users and connected devices from spam, malware, hacking attempts, data breaches, and email spoofing.
SecurityGateway for Email has been improved with new features to identify and categorize spam, enhance interactivity with custom mail flow charts, improve integration with Microsoft 365, and more. Here’s a brief summary. More complete details can be found in the SecurityGateway release notes.
We’re excited to announce that Door Tablet integration is now available in MDaemon! This powerful combination brings even greater efficiency and visibility to your room scheduling and calendar management.
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.
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.

Many businesses are finding that the email security and spam filtering features in Microsoft 365, Barracuda and other secure email gateway platforms just don't seem to get the job done in protecting businesses from spam, phishing, malware and data leaks. SecurityGateway™ for Email is a user-friendly alternative that includes anti-spam, anti-spoofing, and anti-abuse features, along with archiving and compliance, in an easy-to-use interface that includes color-coded email delivery charts & graphs to make administration & troubleshooting easy.
Many organizations that once shifted email and productivity workloads to Microsoft 365 (Office 365) are now “repatriating” them to on-premise email servers. This trend is highlighted by several key drivers – financial, technical, compliance and control. In practice, businesses cite soaring cloud costs, regulatory/data-sovereignty concerns, performance/reliability issues and a desire for tighter control as motivating factors. In this post, we summarize these reasons and note key examples when possible.
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.
TLS (Transport Layer Security) is a cryptographic protocol that allows secure communication over a network. It uses a certificate issued by a trusted CA (certificate authority) to encrypt connections between clients and servers. These certificates must be renewed periodically to ensure continued data privacy.
