Difference between revisions of "Dovecot and Postfix Hybrid Authentication Example"

Revision as of 14:25, 13 February 2014

This guide assumes you already have postfix installed, dovecot installed, and at minimum have email established for unix accounts either by final destination or virtual alias domains. Now you want to set up a separate virtual user database, and these virtual users that do not have a unix account on the system will be able to retrieve their email from their virtual mailbox. The security benefit is in that email only users need not have any security credentials in the /etc/passwd and still be able to pop or imap in and retrieve email.

It might make things more clear to first Understand Postfix Account Types for a Linux system.

configure postfix

Locate your postfix configuration files, they might be in /etc/postfix, or /etc/mail/postfix, or /etc/mail depending on your distro and installation.
