SecurityPlus for MDaemon - Proactive, Layered, Dependable


MDaemon Mail Server
This version: v11.0.0
[Get download]

After downloading MDaemon, we highly recommend reading our Quick install and Configuring MDaemon to deal with spam guides which are available in our MDaemon documentation archive.

Minimum system requirements for MDaemon are available here.

If you are installing MDaemon, or either of its plug-ins for the first time, the software will generate a 30 day unrestricted trial licence for you to use - to continue using the product after your trial period has expired you will need to purchase a licence key which you then simply replace the trial licence key with - no further installation or configuration will be required.

To upgrade an existing installation simply download the latest release from above and install over the top of your current installation - all your current settings will be retained but it is good practice and highly recommended that you always make a back-up of your existing installation prior to upgrading!

We are definitely proud of MDaemon. It is a very stable, efficient and cost effective system. We never had ANY problem with it since 2.5 years.

We also install MDaemon in many customer locations, and they are also very happy with the product. We have installed it on some super yachts, connected to Internet via satellite connection. This is a very important kind of installation, without any possibility to go onboard to fix the problems if they happened (they are all over the world). We had no problem at all.
