How to use the MDaemon or SecurityGateway Let's Encrypt script when a space exists in the directory path

Use the syntax below to generate a Let's Encrypt certificate when a space exists in the MDaemon or SecurityGateway directory path.

This process requires the Let's Encrypt script to be ran manually.  A Windows task can be created using the Windows Task Scheduler to automatically run the command before the certificate expires.

Open a command prompt and navigate to the LetsEncrypt folder in the directory where the software was installed.

  • Example: C:\Program Files\MDaemon\LetsEncrypt>

The command must be ran from inside MDaemon's LetsEncrypt folder and should resemble the following;

  • C:\Program Files\MDaemon\LetsEncrypt> C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe .\letsencrypt.ps1 "-alternatehostnames mail1.domain.com,mail2.domain.com" -To "admin@yourdomain.com"


Find the directory path for powershell.exe.

  • Example: C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe

The command would resemble as follows if ran from this directory.

  • C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe -Command "& 'C:\Program Files\MDaemon\LetsEncrypt\letsencrypt.ps1' -alternatehostnames mail1.domain.com,mail2.domain.com"
