If a certificate was valid when transmitted but has expired before the e-mail is retrieved from the mail server to the client computer, the e-mail may not be retrieved.
If an error occurs outside the validity period of the certificate when an S/MIME e-mail is sent automatically using Memory Transmission or at a specified time, the error will be reported by plaintext e-mail to the e-mail address of the sender or administrator. The error details can be viewed in the job log. When using S/MIME, be sure to enable the job log collection function. For details about viewing the logs, see Managing Log Files.
