This file is used in configurations in which the server does not run directly on Internet, but acts as internal mail exchanger and external mail gateway. This file defines 'Return-Path: <...>' mapping for internal mail delivery. If used some Mail client like Outlook, Eudora, KMail, etc, you have to configure your email address with the external account, say 'axmsuser@axmsserver.org'. When you post an internal message to 'foo@home.bogus', the mail client puts your external email address ('axmsuser@axmsserver.org') in the 'MAIL FROM: <...>' SMTP request. Now if the user 'foo' replies to this message, it replies to 'axmsuser@axmsserver.org', and then is sent to the external mail server. With the entry above in 'EXTALIASES.TAB' file the 'Return-Path: <...>' field is filled with 'axmsuser@home.bogus' that leads to an internal mail reply.

You 'CANNOT' edit this file while AfterLogic XMail Server is running because it is an indexed file.
