About

SuperMailOS is managed business email on your own domain for small teams. You bring your domain; SuperMailOS runs the mail server and handles deliverability — SPF, DKIM, DMARC, IP reputation, and warmup — so your email lands in the inbox, not the spam folder. Setup takes minutes: verify your domain with one-click DNS on Cloudflare, DigitalOcean, and other providers (or guided copy-paste on any registrar), invite your team, and start sending. Every person gets a real mailbox; aliases like hello@ and support@ are unlimited and free. Webmail is as simple as Gmail — threads, instant search, keyboard shortcuts, labels, dark mode — plus IMAP and SMTP for any mail app, and a live deliverability dashboard showing your mail landing. Flat pricing per mailbox: Pro $3/mailbox/month annually (10 GB, 3 domains), Business $5 (30 GB, unlimited domains), custom at 50+. 14-day free trial, no credit card.

Pros & Cons from Real Users

Pros

  • No doubt it is simple to handle plus a tons of SPAM/Security controlling options. Over it is a good quality email server, providing great features and customer support as we are using for the past 20 yrs.
  • The system is easy and intuitive, it gives system administrator completely visibility and control.
  • We started using Mdaemon email in 2007. True to their words, Mdaemon installation was problem-free and flawless. The help desk reached out to us during installation for support. But, we did not need any support as installation was simple and straight forward. It was easy to install, configure and use even for a non technical person.
  • We started to use MDeamon software on our own server back with version 9 many years ago. Over the years they have made so many improvements to not only the email features, adding docs and file sharing to an entire domain or just one single user. Among other great improvements to the web UI such as layout and ease of use, and also greatly improving the security gateway for spam. Now we have migrated to the hosted platform, same great software, and support without the costly upgrading of new servers, OS versions, and hardware costs.
  • The password check, complex password option, and robust a/v engines are just a few of the features we love about MDaemon. They line up well with our ongoing security initiatives.

Cons

  • Cant integrate with SSO and no appliance based. There is nothin much to dislike about this software. AltN has implemented features over time that are important to our requirements."
  • The system not 100% exchange compatible, may affect some demanding clients user experience.
  • Sometimes the system is memory hungry. This can cause the system to slow.
  • In the past, older versions were some what of a pain to migrate to a newer version of the software. But they have made great efforts to make this transition easier for the network admins over the years. The only other feature i would say is lacking is a way for a user to create or download a backup of their entire email account, settings, and files.
  • We were disappointed when the built in encryption for webmail was discontinued.
