You can attach one or several files to a message you want to send. Click the Browse button (or a similar button your browser displays for "file-type" fields) and select a file on your local disk (i.e. on the disk attached to the computer that runs your Web browser software). The name of the selected file appears in the Attachment field. Use other Attachment fields to send several files with your message.
Note: you should attach files after all other message fields are filled. If you click any button (for example, a button that opens the Address Book), the file selection will be cleared and you will have to select the files again.
The Composer page allows a user to specify the message subject, to enter the recipient address(es), to specify if the DSN (Delivery Status Notification) and/or MDN (Message Disposition Notification) is required, to enter the message text, and to attach files to a message.
