In the recipient no-display mode, the recipient addresses will be put in Bcc:. Therefour, the recipients will not see the mail addresses to be sent. However, if "Copy to sender" is set to "valid" in the administrator setup screen, the email sender recieves will have Bcc: information.
In the sender no-display mode, the sender mail will be displayed in the header of mail as usual. But mail address is shown as a dummy address which administrator sets in the administration setup. Since this is a dummy and may not exist, "Copy to sender" may no longer work. If you turn on "Copy to sender" in the admin setup, the mail will be sent to the dummy address which may not be valid and it causes mail server screwing up. If the dummy address is valid and really exists, the copy will be sent to the valid dummy address.
Some providers or mail servers prevent to send emails from the one who uses an invalid email address. In such case, you cannot send email to anyone as long as you use the sender no-display mode.
Please understand the above when you use the sender no-display mode.
