## [Renew MDaemon & SecurityGateway for the Latest Features & Improved Security!](https://blog.mdaemon.com/expiring-support-for-older-software-renew-upgrade-for-the-latest-features-improved-security)

As our products have evolved over the years, with new features added regularly, older versions of our software are eventually no longer supported. In this post, we'll highlight new features added recently to MDaemon and SecurityGateway, including AI Email Classification, QR Code Detection, and much more.
**Effective March 1, 2026, technical support was discontinued for the following product versions:**
- MDaemon Email Server - Versions 21.x and below
- MDaemon Connector for Outlook - Versions 6.x and below
- SecurityGateway for Email Servers - Versions 7.x and below
For continued support, this is a great opportunity to renew your license and upgrade to the most recent versions of our software to take advantage of the latest features! As a current user, you can [save up to 50% off a new MDaemon Email Server license](https://mdaemon.com/pages/software-renewal-discount-program) by renewing before your license expires (20% off if it has already expired), with additional renewal discounts available on MDaemon Connector for Outlook and MDaemon ActiveSync.
Phishing and business email compromise attacks cost organizations more than $2.77 billion in 2024 alone, according to the FBI's Internet Crime Complaint Center, and AI-generated phishing attempts have become dramatically more common in the last year. Running unsupported software means missing the security protections designed to help defend against exactly these kinds of threats.
## **Upgrade MDaemon today and get these exciting new features:**
- QR code detection to help stop "quishing" (QR code phishing) attacks
- Single Sign-on for Webmail using OpenID Connect (OIDC)
- Passwordless, WebAuthn-based authentication and a built-in Security Health Check
- Integrated web conferencing in Webmail, including audio, video, and screen sharing
- DMARC filtering enabled by default for new installations, along with ARC (Authenticated Received Chain) support
- ...and much more!
