Compose your email message.
Choose Add File from the Attachments menu in the Compose window.
The Mailer - Attachments - Add dialog box is displayed.
(Optional) Click the Keep dialog box open on desktop check box.
Clicking this option box indicates that you do not want the dialog box to close after the Add button is clicked. This action eliminates the need to choose Add File from the Attachments menu to add more than one attachment.
Select a file to attach and click Add.
The attachment is added to the attachment list in the lower portion of the Compose window.
To remove an attachment you just added, select its icon and choose Delete from the Attachments menu.
To restore a deleted attachment, choose Undelete from the Attachments menu.
(Optional) Choose Rename from the Attachments menu to change the name of a selected attachment.
If you drag and drop messages from the Message Header List in the main window to the attachment list, Mailer creates one mailbox that contains all of the messages.
