The Header Translation feature can change any portion of text found within a header to a new value whenever a message is detected which must leave your domain destined for a remote host. You specify the text you want to search for and its corresponding replacement value. MDaemon will then search through all the headers in the message and make the replacements. You may also specify headers that MDaemon should not modify (such as "Subject:" or "Received:" headers) by clicking the Exceptions button on this dialog.

This feature is necessary for some MDaemon configurations in which the local domain name is fictitious or different from the domain name that must appear on outbound mail. In such a situation, Header Translation could be used to change every occurrence of "@localdomain" to "@RemoteDomain".
