SSL and MailNow! 5


This document explains how to import a certificate, how to create a self-signed cert, and how to use an imported cert to configure SSL for SMTP, POP3 and IMAP.

 

To configure SSL, you need to have an SSL certificate and the certificate must be imported. Note that you can use a real commercial certificate issued by a commercial Certificate Authority (CA) or you may use a self-signed certificate. MailNow! 5 even has the ability to create self-signed certificates which you can use to easily enable SSL.

 

 

1.1.      How to import SSL certificate in MailNow! 5

 

  • In the navigation menu on the left, click on System Setting | Security | Certificates

To import a certificate click on the Import menu which is circled in red in  Screen shot 2.0. An import SSL Certificate dialog box will appear as shown in Screen shot 3.0.

  • Click “Select” to find your .pfx1 file which contains the certificate.
  • Provide the certificate’s password, then click on the “Import” button. You will come back to the same window like the one shown in Screenshot 2.0. Here, now you can see the detail of your certificate which you have imported just now.

1.2.      How to generate SSL certificate in MailNow! 5

 

  • Go to System Settings | Security | Certificates.
  • Click on “Generate” which is circled in red in Screen shot 4.0

             

                                      Screen shot 4.0

  • The Generate SSL Certificate dialog box will appear as shown in Screenshot 5.0
  • Complete the fields by providing the relevant details.

 

o   You may give any name for the Certificate filename.

o   The Issued To field should be your company name.

o   The Password field will be the password that will be used to protect the generated certificate.

    Keep this password safe as you might need to use it in the future.

o   The Valid To date is the expiry date of this certificate. By default MailNow! sets it to 10 years from the current date.


  • Finally click on the “Generate” button to complete generating your own self-signed SSL certificate.
  • Once you have done so you will be back to the similar window shown in Screenshot 4.0 where your newly generated certificate will be listed in detail.

Note:

If you do not see the certificate that you want to use, you need to import the certificate first. You may need to refer section 1.1. How to import SSL certificate in MailNow! 5 above.
