If you wish to view e-mails sent using CMD's internal e-mail client, click Tools | E-Mail | View Sent E-Mails. This brings up the view sent e-mails dialog:
There are columns in the upper pane for Subject, Sender, and Date (which can be resized to look best on your monitor), and Addressee pane that will display all the addresses to which the e-mail was sent, and the message pane (located in the lower portion of the dialog) that displays the actual message. You can resize the grid with the Subject, Sender, and Date info, and you can resize the Addressee page.
If you want to see the additional info that's available about a sent e-mail such as ISP used, return e-mail address used, and the name of an attached file(s), click the More Info button.
If you wish to delete an e-mail from the Sent E-Mails file, click on the Subject/Name/Date line of the e-mail you wish to delete and then click the Delete button.
