Postfix Manual Pages

Information for new Postfix users

New Postfix users should first look at the following introductory documents. These introductions are hyperlinked to more advanced documents and to UNIX-style manual pages. The UNIX-style manual pages are intended for people who are already familiar with Postfix.

• Postfix architecture overview
• Basic configuration
• Trouble shooting
• Content inspection overview
• Relay/access control overview
• Lookup table overview

Postfix manual page organization

Each Postfix manual page is numbered after a section of the UNIX manual: examples are mailq(1) or access(5). Unfortunately, there is no single universal method to organize manual pages; each UNIX flavor appears to be different. Postfix documentation assumes the following convention:
