• If a certificate was valid when transmitted but has expired before retrieving the e-mail 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 sending an S/MIME e-mail
automatically, such as in the case of sending e-mail by Memory Transmission or at a specified time,
the error will be reported by e-mail in plain text to the sender's or administrator's e-mail address.
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 page 203 "Managing Log Files".
