PMMail not only supports the "To:" and "CC:" functions, but you can also use the "BCC:" function of e-mail. What BCC does is sends a copy of the message to a person without notice (i.e., "blind") to persons listed in the To: and CC: fields.

While you are addressing a new e-mail message, simply click on the button labeled "CC". You will find this button located next to the CC entry field. If you click it once, it will turn into BCC. By clicking on the CC: and the BCC: buttons, a user can use both the CC: and the BCC: functions in a single e-mail.
