'''Postfix''' is a free software / open source mail transfer agent (MTA), a computer program for the routing and delivery of email. It is intended as a fast, easy-to-administer, and secure alternative to the widely-used Sendmail MTA.

==Base configuration==
The [http://www.postfix.org/postconf.5.html main.cf] file stores site specific Postfix configuration parameters while [http://www.postfix.org/master.5.html master.cf] defines daemon processes. The [http://www.postfix.org/BASIC_CONFIGURATION_README.html Postfix Basic Configuration] tutorial covers the core settings that each site needs to consider.

Configuration settings for a few common environments are discussed in [http://www.postfix.org/STANDARD_CONFIGURATION_README.html Postfix Standard Configuration Examples].

Address rewriting and mail routing are covered in [http://www.postfix.org/ADDRESS_REWRITING_README.html Postfix Address Rewriting]. The full documentation collection is at [http://www.postfix.org/documentation.html Postfix Documentation].

===Examples===
postalias /etc/postfix/aliases
Then create <code>/etc/postfix/aliases.db</code>
postfix reload
postconf -n
postfix check
