I have successfully compiled, configured and ran Dovecot with virtual users feature.

Here's part of my /etc/dovecot.conf configuration file:

mail_location = maildir:/home/%d/%n/Maildir

auth default {
    mechanisms = plain login

    userdb passwd-file {
        args = /home/%d/etc/passwd
    }
    passdb passwd-file {
        args = /home/%d/etc/shadow
    }

    socket listen {
        master {
            path = /var/run/dovecot/auth-worker
            mode = 0600
        }
    }
}

I faced one issue I can't resolve myself. Is there anyway to create users' domains mapping and provide username in mail_location?

Examples: 1. currently I have /home/domain.com/user/Maildir 2. I'd like to have /home/USER/domain.com/user/Maildir

Can I achieve this somehow?
