The following table lists some minor known issues.
|307919||Webmail GUI for IBE users displays a paper clip for all email although the email has no attachments.|
|381511||IBE messages are not signed with DKIM although DKIM signing is enabled.|
|(No bug ID)||Due to more confining security restrictions imposed by the iOS system, email attachments included in IBE PUSH notification messages can no longer be opened properly on iOS devices running version 10 and up. Therefore, users cannot view the encrypted email messages on these iOS devices. Users should download and open the attachments on their PCs as a workaround.|
