Upload Certificate Bundle Manually

This feature is only really needed if you want to re-use an existing certificate rather than the automatically generated Let's Encrypt certificate (Let Mail Assure manage your public certificate).

Create bundle file

Before uploading the certificate bundle into Mail Assure, the certificate chain needs to be saved as a bundle file. This is a single file containing the private key, any intermediate certificates and the Certification Authority (CA) certificate in a single file:

1. Export the required key and certificate(s) to text files
2. Create a file locally with a .pem extension, containing the following data:

   Replace text in italic (including "<" and ">") with your personal data

   - - - - - BEGIN PRIVATE KEY - - - - -
   <Private key from server used to generate the CSR>
   - - - - - END PRIVATE KEY - - - - -
   - - - - - BEGIN CERTIFICATE - - - - -
   <Certificate code provided by the certificate issuer>
   - - - - - END CERTIFICATE - - - - -
   - - - - - BEGIN CERTIFICATE - - - - -				
   <Intermediate certificates provided by the issuer (not always provided, root CA cert (below) may be enough in some cases)>
   - - - - - END CERTIFICATE - - - - -
   - - - - - BEGIN CERTIFICATE - - - - -				
   <Root certificate provided by certificate issuer>
   - - - - - END CERTIFICATE - - - - -

3. Save the file to a temporary location
