When S/MIME Cannot Be Used

This section describes likely causes of and possible solutions for S/MIME-related problems.

Problem	Cause	Solution
If several destinations are selected for the broadcasting sequence, the data is sent over twice.	Encrypted e-mails are sent to the destinations for which S/MIME authentication is set, and plain text e-mails are sent to the destinations for which S/MIME authentication is not set.	Make sure S/MIME-authentication destinations are separate from plain text destinations. Contact the administrator for details about destination settings.
When putting a signature on an e-mail using S/MIME, an e-mail address for "Sender" is not set for "From".	When S/MIME is applied, the administrator appears in the "From" field, and the sender appears in the "Reply-to" field.	Contact the administrator.

Problem

Cause

Solution

If several destinations are selected for the broadcasting sequence, the data is sent over twice.

Encrypted e-mails are sent to the destinations for which S/MIME authentication is set, and plain text e-mails are sent to the destinations for which S/MIME authentication is not set.

Make sure S/MIME-authentication destinations are separate from plain text destinations.

Contact the administrator for details about destination settings.

When putting a signature on an e-mail using S/MIME, an e-mail address for "Sender" is not set for "From".

When S/MIME is applied, the administrator appears in the "From" field, and the sender appears in the "Reply-to" field.

Contact the administrator.

Using S/MIME makes e-mail larger than when not using S/MIME.
