Setup Postfix and Dovecot on Debian Squeeze with users stored text-file
Challenge
In the following article I will explain how to setup postfix and dovecot on debian squeeze using virtual users stored in a text-file.
I wanted to setup a mail system which supports local mailboxes via imap and pop3. Next the mail server should provide connections using SSL / TLS.
Finally every users account should only be a virtual user account which is stored in a text-file instead of a MySQL database.
