Diagnose "Certificates" checks the expiration of certificates that are provided in the MailSealer (S/MIME) or / and Web SSL certificates (WEB SSL) depending on the selected test type. The result is shown in either green (OK), yellow (Warning) or red (Expired) color. This is useful to automaticly check certificates for expiration, especially if there is a large number of them. Expired S/MIME certificates would result in a failure of mail encryption, unless they have not been trusted manually.
The Diagnose is useful for the REDDOXX Administrator to Monitor expired, or for expiration marked certifikates in order to update them accordingly.
Further Information to update/upload certificates can be found in the documention for MailSealer and SSL certificates.
