When an email software is used that does not support the digital signature

When using certain email software that does not support this signature, the email message will display but the file "smime.p7s" is attached to the email as the digital certificate.
The electronic signature cannot be confirmed even if the attached file is opened.

In addition, the procedure for checking the digital signature varies depending on the email software. When using another email software that is not Microsoft Outlook 2013, contact the software provider about the specific procedure for checking the digital signature.
