Hi there. I've gone carefully through the steps to get postfix, courier, mysql et al working per the tutorial. Unfortunately, users aren't being recognized. When I send a message to the sample user I created, it bounces. <firstname.lastname@example.org>: unknown user: "ben" Reporting-MTA: dns; byrnecreative.com X-Postfix-Queue-ID: 24E20159C834E X-Postfix-Sender: rfc822; email@example.com Arrival-Date: Sun, 10 Aug 2008 20:13:57 -0400 (EDT) Final-Recipient: rfc822; firstname.lastname@example.org Original-Recipient: rfc822;email@example.com Action: failed Status: 5.1.1 Diagnostic-Code: X-Postfix; unknown user: "ben" Additionally, when I check /home/vmail nothing's been created. /var/log/mail.log gives some trivial-rewrite warnings but nothing else looks out of the ordinary, just logs that the user is unknown and bounces it back. Any help anyone could provide would be great.
