By default, Mail Assure automatically generates and manages the installation of a publicly signed TLS certificate on your server for HTTP, SMTP and IMAP. The certificate is automatically renewed when it is due to expire. This option fits most scenarios and means you don't have to go through the lengthy certificate request and upload process.
In some situations, however, you may want to manage your own certificates. For example, if your Mail Assure system is embedded within another system that has its own certificates, you may need to use the same certificates used by the host system - to avoid complications, or if you prefer to use a certificate from another or specific certification authority. You can replace these certificates with a signed certificate manually, see Upload Certificate Bundle Manually.
You can also choose to manage the entire SSL certificate process manually, see Manage your own SSL Certificates.
