OK, I followed this tutorial: http://workaround.org/articles/ispmail-sarge/ Everything works except for local users (with their own home directory and Maildir). I am unable to login using my mail client (Outlook Express). If I view my mail.log all I see is "Login Failed". Outlook Express reports a username/password error. I've tried with the user entered in mysql and without and with the same password as the real user and without and it doesn't make any difference. My users listed in mysql that do not have local user accounts work fine. Does anyone know what is causing this? Here's my postfix/main.cf:
Do these local users use the same domain as your virtual users (from the database)? This doesn't work. Your local users must use a domain that is not in the database.
