How to create a CSR and import a third-party SSL certificate for MDaemon using Certreq

MDaemon does not have a method of creating a Certificate Signing Request (CSR) for you in order to obtain a third party SSL certificate issued by a Trusted Root Authority (such as Verisign or GoDaddy). In the past, we have recommended installing Internet Information Server (IIS) and using it to generate the certificate request, but that may be difficult for Administrators who are not used to working with that product or who do not wish to install IIS on their server. Windows has a command line utility, certreq.exe that will allow you to create a certificate request and import the new certificate into the Windows Certificate Store, where it can be used with MDaemon.

The example below will generate a CSR for a 2048 bit key length certificate.

  1. Purchase an SSL Certificate from an issuing authority.
  2. Create the Certificate Signing Request (CSR): 
    1. Log into your mail server using an Administrator account.
    2. Create a file named CSRParameters.inf on the C:\ drive using the contents below as a template:

      	        [NewRequest]
      	        Subject="CN=mail.example.com,OU=Research In Motion Limited,O=Research In Motion Limited,S=Nevada,L=Las Vegas,C=US"
      	        KeySpec=1
      	        KeyLength=2048
      	        Exportable=TRUE
      	        MachineKeySet=TRUE
      	        SMIME=False
      	        PrivateKeyArchive=FALSE
      	        UserProtected=FALSE
      	        UseExistingKeySet=FALSE
      	        ProviderName="Microsoft RSA SChannel Cryptographic Provider"
      	        ProviderType=12
      	        RequestType=PKCS10
      	        KeyUsage=0xa0
      	        Silent=TRUE
      	        [EnhancedKeyUsageExtension]
      	        OID=1.3.6.1.5.5.7.3.1
      	        
    3. Open a command prompt.
    4. Change the directory to the C:\ path. 
    5. Type in the following command:
      C:\>certreq -new CSRParameters.inf CSROutput.pem 
    6. Open Windows Explorer and browse to the C:\ directory to locate the CSROutput.pem file.
    7. Using the CSROutput.pem file, go back to the certificate authority and use the file to request your certificate.
  3. Install the certificate:
    1. Download the certificate as a .crt file
    2. On the server, open a command prompt.
    3. Navigate to the directory that contains the CRT file (C:\ in this example).
    4. Enter the following command (substitute mail.example.com.crt for the actual name of the .crt file you received from the certificate authority):
      C:\>certreq -accept mail.example.com.crt
  4. The certificate will now be available in MDaemon when SSL/HTTP configurations have been created.
