Compose Window Custom Header Fields

The header of your Compose window always has To, Subject, and Cc fields. In addition, Bcc is available via the Header menu. You can add custom headers to the Header menu by adding them to the Custom Fields scrolling list on the Compose Window Properties category.

Some useful headers that you might want to use are the following:

• Precedence: junk -- If the mail system cannot send a message with this header, the message will not be "bounced" back to you. This is handy if you are sending out a message to a large alias, and you do not wish to receive notices whenever the message cannot be delivered to an individual.

• Reply-To: email address -- When you reply to a message with this header, the reply is sent to the email address in the Reply-To: header field (instead of being sent to the sender of the message).

• Return-Receipt-To: email address -- When you send a message with this header, you will receive a "Return Receipt" from the mail system when the message is successfully delivered.

To create a custom header field, follow these steps:

1. Type the label for the field in the Header Field line of the Properties window.

   Do not type a colon following the label. The colon is automatically provided by Mail Tool.

2. If you want the field to be filled in with a default value, type this value in the Default Value field.

3. Choose either Before or After from the Add menu to add the new header field to the scrolling list.

4. To apply the change to Mail Tool, click SELECT on the Compose Window Properties Apply button.

5. To include the new header field in a mail message, choose the item from the Compose window Header menu, as shown in the menu at the left.
