This howto I put together very quickly becasue of the late requsts on tsl-discuss. So there are no explenations but just a quick list on things to do to make ostfix, courier-imaps, and MySQL work with Maildir and Virtual Domains.

Have fun :-)

Install packages

1. of all you need to have installed these packages:

• Apache 2
• MySQL 4
• PHP
• stfix
• Postfix-MySQL
• Courier-imap
• Courier-imaps
• Courier-imap-MySQL

Filesystem

Secondly you will need to make these system changes:
In my example i use /data/mail for maildirs and domains.

yourbox:~# mkdir -p /data/mail/
yourbox:~# chmod -R 775 /data/mail/
yourbox:~# chown -R postfix:postfix /data/virtual/

Authorisation

For MySQL you need to change the authorization in /etc/courier-imap/authdaemonrc Set autmodulelist to "authmysql" Now change /etc/courier-imap/authmysqlrc set:

MYSQL_SERVER            localhost
MYSQL_USERNAME          yourusername
MYSQL_PASSWORD          yourpassword
MYSQL_SOCKET            /var/run/mysql/mysql.sock
MYSQL_DATABASE		maildb
MYSQL_USER_TABLE      	users
MYSQL_HOME_FIELD       '/data/mail/'
MYSQL_MAILDIR_FIELD   	maildir
MYSQL_WHERE_CLAUSE  	imapok=1 AND bool1=1 AND bool2=1
