-Sender and also recipient can be rewritten using regular expression or by simple combination of key:value. During mail delivery postfix examine file line by line and if match is found then address from this line is used. Configuration type <code>regexp</code> is read by postfix directly so it is not necessary to create binary representation via command postmap.

+Both of them rewrite also <code>postmaster</code> and "empty" source used for bounce message. If you would like to use such a configuration then make sure that system accounts (postmaster, double-bounce, root, etc.) are in configuration so you will not end up with bounce loop.

	This is short guide how to setup postfix to use another server as email relay. Most of the dynamic IP address assigned to broadband (home) network are blacklisted. This is desired behavior as users should use email service instead of direct email delivery. If your are using server or Linux box to send notifications from local services then you may find problem to deliver such a notifications. Configuration of postfix is flexible and it is possible to configure it to act as "user" which use user/pass for authentication. Once postfix is authenticated on relay host it's possible to send emails through it. Here is example how to configure postifx in this way:		This is short guide how to setup postfix to use another server as email relay.
