-In previous articles, we discussed how to set up your own mail server on Debian from scratch. In [[tutoriaux:install-email-server-part-1|part 1]] and [[tutoriaux:install-email-server-part-2|part 2]] of this tutorial series, we learned how to set up **Postfix SMTP server** and **Dovecot IMAP server**, but so far we can only have email addresses for users with local Unix account.

 With **virtual mailboxes**, we don’t need to create local Unix account for each email address. If you are going to set up a mail server for a company or organization, it’s always better to have an easy way to create virtual mailboxes in a web-based interface, which also allows users to change their passwords. That’s where PostfixAdmin comes in. With **virtual mailboxes**, we don’t need to create local Unix account for each email address.
